Now that vxsqrt and vxsnan are computed directly by softfloat,
we don't need to recompute it. Split out float_invalid_op_sqrt
to be used in several places. This fixes VSX_SQRT, which did
not order its tests correctly to eliminate NaN with sign set.

This commit fixes the difference reported in the bug in the reserved
bit 52, it does this by adding this bit to the mask of bits to not be
directly altered in the ppc_store_fpscr function (the hardware used to
compare to QEMU was a Power9).
The bits 0 to 27 were also added to the mask, as they are marked as
reserved in the PowerISA and bit 28 is a reserved extension of the DRN
field (bits 29:31) but can't be set using mtfsfi, while the other DRN
bits may be set using mtfsfi instruction, so bit 28 was also added to
the mask.
Although this is a difference reported in the bug, since it's a reserved
bit it may be a "don't care" case, as put in the bug report. Looking at
the ISA it doesn't explicitly mention this bit can't be set, like it
does for FEX and VX, so I'm unsure if this is necessary.

mtfsf, mtfsfi and mtfsb1 instructions call helper_float_check_status
after updating the value of FPSCR, but helper_float_check_status
checks fp_status and fp_status isn't updated based on FPSCR and
since the value of fp_status is reset earlier in the instruction,
it's always 0.
Because of this helper_float_check_status would change the FI bit to 0
as this bit checks if the last operation was inexact and
float_flag_inexact is always 0.
These instructions also don't throw exceptions correctly since
helper_float_check_status throw exceptions based on fp_status.
This commit created a new helper, helper_fpscr_check_status that checks
FPSCR value instead of fp_status and checks for a larger variety of
exceptions than do_float_check_status.
Since fp_status isn't used, gen_reset_fpstatus() was removed.
The hardware used to compare QEMU's behavior to was a Power9.

The CPNC portion of the diag318 data is erroneously reset during an
initial CPU reset caused by SIGP. Let's go ahead and relocate the
diag318_info field within the CPUS390XState struct such that it is
only zeroed during a clear reset. This way, the CPNC will be retained
for each VCPU in the configuration after the diag318 instruction
has been invoked.
The s390_machine_reset code already takes care of zeroing the diag318
data on VM resets, which also cover resets caused by diag308.

The calculation of the length of TLB range invalidate operations
in tlbi_aa64_range_get_length() is incorrect in two ways:
* the NUM field is 5 bits, but we read only 4 bits
* we miscalculate the page_shift value, because of an
off-by-one error:
TG 0b00 is invalid
TG 0b01 is 4K granule size == 4096 == 2^12
TG 0b10 is 16K granule size == 16384 == 2^14
TG 0b11 is 64K granule size == 65536 == 2^16
so page_shift should be (TG - 1) * 2 + 12
Thanks to the bug report submitter Cha HyunSoo for identifying
both these errors.

In the SSE decode function gen_sse(), we combine a byte
'b' and a value 'b1' which can be [0..3], and switch on them:
b |= (b1 << 8);
switch (b) {
...
default:
unknown_op:
gen_unknown_opcode(env, s);
return;
}
In three cases inside this switch, we were then also checking for
"if (b1 >= 2) { goto unknown_op; }".
However, this can never happen, because the 'case' values in each place
are 0x0nn or 0x1nn and the switch will have directed the b1 == (2, 3)
cases to the default already.
This check was added in commit c045af25a52e9 in 2010; the added code
was unnecessary then as well, and was apparently intended only to
ensure that we never accidentally ended up indexing off the end
of an sse_op_table with only 2 entries as a result of future bugs
in the decode logic.
Change the checks to assert() instead, and make sure they're always
immediately before the array access they are protecting.

For A64, any input to an indirect branch can cause this.
For A32, many indirect branch paths force the branch to be aligned,
but BXWritePC does not. This includes the BX instruction but also
other interworking changes to PC. Prior to v8, this case is UNDEFINED.
With v8, this is CONSTRAINED UNPREDICTABLE and may either raise an
exception or force align the PC.
We choose to raise an exception because we have the infrastructure,
it makes the generated code for gen_bx simpler, and it has the
possibility of catching more guest bugs.

This reverts commit 9fcd15b9193e819b6cc2fd0a45e3506148812bb4.
This change turns out to cause regressions, for instance on the
imx6ul boards as described here:
https://lore.kernel.org/qemu-devel/c8b89685-7490-328b-51a3-48711c140a84@tribudubois.net/
The primary cause of that regression is that the guest code running
at EL3 expects SMCs (not related to PSCI) to do what they would if
our PSCI emulation was not present at all, but after this change
they instead set a value in R0/X0 and continue.
We could fix that by a refactoring that allowed us to only turn on
the PSCI emulation if we weren't booting the guest at EL3, but there
is a more tangled problem with the highbank board, which:
(1) wants to enable PSCI emulation
(2) has a bit of guest code that it wants to run at EL3 and
to perform SMC calls that trap to the monitor vector table:
this is the boot stub code that is written to memory by
arm_write_secure_board_setup_dummy_smc() and which the
highbank board enables by setting bootinfo->secure_board_setup
We can't satisfy both of those and also have the PSCI emulation
handle all SMC instruction executions regardless of function
identifier value.
This is too tricky to try to sort out before 6.2 is released;
revert this commit so we can take the time to get it right in
the 7.0 release.

Commit cff03145ed3c ("sev/i386: Introduce sev_add_kernel_loader_hashes
for measured linux boot", 2021-09-30) introduced measured direct boot
with -kernel, using an OVMF-designated hashes table which QEMU fills.
However, no checks are performed on the validity of the hashes area
designated by OVMF. Specifically, if OVMF publishes the
SEV_HASH_TABLE_RV_GUID entry but it is filled with zeroes, this will
cause QEMU to write the hashes entries over the first page of the
guest's memory (GPA 0).
Add validity checks to the published area. If the hashes table area's
base address is zero, or its size is too small to fit the aligned hashes
table, display an error and stop the guest launch. In such case, the
following error will be displayed:
qemu-system-x86_64: SEV: guest firmware hashes table area is invalid (base=0x0 size=0x0)
