tcg/optimize: fix setcond2 optimization

When setcond2 is rewritten into setcond, the state of the destination
temp should be reset, so that a copy of the previous value is not
used instead of the result.

tcg-arm: Use movi32 in exit_tb

Avoid the mini constant pool for armv7, and avoid replicating
the test for pre-v7.

tcg-arm: Fix 64-bit tlb load for pre-v6

Found by inspection, since the effect of the bug was simply to
send all memory ops through the slow path.

tcg-arm: Improve scheduling of tcg_out_tlb_read

The schedule was fully serial, with no possibility for dual issue.
The old schedule had a minimal issue of 7 cycles; the new schedule
has a minimal issue of 5 cycles.

tcg-arm: Use movi32 + blx for calls on v7

Work better with branch predition when we have movw+movt,
as the size of the code is the same. Perhaps re-evaluate
when we have a proper constant pool.

tcg-arm: Convert to CONFIG_QEMU_LDST_OPTIMIZATION

Move the slow path out of line, as the TODO's mention.
This allows the fast path to be unconditional, which can
speed up the fast path as well, depending on the core.
