The replacement isn't ideal, as the raw count of bits
is not easily synced with exec/cpu-all.h, but it does
remove from tcg.h the target dependency on TARGET_PAGE_BITS_MIN
which is built into TLB_FLAGS_MASK.

In preparation for compiling tcg/ only once, eliminate
the all_helpers array. Instantiate the info structs for
the generic helpers in accel/tcg/, and the structs for
the target-specific helpers in each translate.c.
Since we don't see all of the info structs at startup,
initialize at first use, using g_once_init_* to make
sure we don't race while doing so.

Removes the only use of TARGET_LONG_BITS from tcg.h, which is to be
target independent. Move the symbol to a define in tcg-op.h, which
will continue to be target dependent. Rather than complicate matters
for the use in tb_gen_code(), expand the definition there.

Disconnect guest page size from TCG compilation.
While this could be done via exec/target_page.h, we want to cache
the value across multiple memory access operations, so we might
as well initialize this early.
The changes within tcg/ are entirely mechanical:
sed -i s/TARGET_PAGE_BITS/s->page_bits/g
sed -i s/TARGET_PAGE_MASK/s->page_mask/g

For 32-bit hosts, we cannot simply rely on TCGContext.addr_bits,
as we need one or two host registers to represent the guest address.
Create the new opcodes and update all users. Since we have not
yet eliminated TARGET_LONG_BITS, only one of the two opcodes will
ever be used, so we can get away with treating them the same in
the backends.
