Both tcg_target_init and tcg_target_qemu_prologue
are unused outside of tcg.c.

Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64
to perform the move at the proper width, which may elide a REX prefix.
Introduce a TCG_TYPE_REG enumerator to represent the "native width"
of the host register, and to distinguish the usage from "pointer data"
as represented by the existing TCG_TYPE_PTR.
Update all targets to match.

Now that the prologue is generated after GUEST_BASE is fixed,
we can load it as an immediate, and also avoid reserving the
register if it isn't necessary.

Branch offsets should only be overwritten during relocation,
to support partial retranslation.

Issue the tlb load as early as possible and perform the address
masking while the load is completing.

Along the tlb hit path, we were modifying the variables holding the input
register numbers, which lead to incorrect expansion of the tlb miss path.
Fix this by extracting the tlb hit path to separate functions with their
own local variables. This also makes the difference between softmmu and
user-only easier to read.

Load from the guest_base variable rather than embed a constant.
Always reserve TCG_GUEST_BASE_REG if guest base support enabled.

Define "M" constraint for and_mask_p and "O" constraint for or_mask_p.
Assume that inputs are correct in tcg_out_ori and tcg_out_andi.

PA-RISC uses procedure descriptors. We'd need to emit a call to
the millicode routine $$dyncall. However, this situation doesn't
actually arise, since we always have the descriptor available at
TCG code generation time.

Handle the output log part overlapping the input high parts.
Also, improve sub2 to handle some constants the second input low part.

Delete inline functions from tcg-target.h that don't need to be there,
move the others to tcg-target.c. Add 'Z', 'I', 'J' constraints for
0, signed 11-bit, and signed 5-bit respectively. Add GUEST_BASE support
similar to ppc64, with the value stored in a register. Add missing
registers to reg_alloc_order. Add support for 12-bit branch relocations.
Add functions for synthetic operations: addi, mtctl, dep, shd, vshd, ori,
andi, shifts, rotates, multiply, branches, setcond. Split out TLB reads
from qemu_ld and qemu_st; fix argument loading for tlb external calls.
Generate the prologue.

Some targets (e.g. Alpha and MIPS64) need to keep 32-bit operands
sign-extended in 64-bit registers (regardless of the "real" sign
of the operand). For that, we need to be able to distinguish
between a 32-bit load with a 32-bit result and a 32-bit load with
a given extension to a 64-bit result. This distinction already
exists for the ld* loads, but not the qemu_ld* loads.
Reserve qemu_ld32u for 64-bit outputs and introduce qemu_ld32 for
32-bit outputs. Adjust all code generators to match.
