Translation logic may partially decode an instruction, then abort and
remove the instruction from the TB. This can happen for example when an
instruction spans two pages. In this case, plugins may get an incorrect
result when calling qemu_plugin_tb_n_insns to query for the number of
instructions in the TB. This patch updates plugin_gen_tb_end to set the
final instruction count.

The tcg/tcg.h header is a big bucket, containing stuff related to
the translators and the JIT backend. The places that initialize
tcg or create new threads do not need all of that, so split out
these three functions to a new header.

A large chunk of ld/st functions are moved from cputlb.c and user-exec.c
to ldst_common.c.inc as their implementation is the same between both
modes.
Eventually, ldst_common.c.inc could be compiled into a separate
target-specific compilation unit, and be linked in with the targets.
Keeping CPUArchState usage out of cputlb.c (CPUArchState is primarily
used to access the mmu index in these functions).
