[PULL 1/3] tcg: Do not kill globals at conditional branches

[Richard Henderson]

We can easily register allocate the entire extended basic block
(in this case, the set of blocks connected by fallthru), simply
by not discarding the register state at the branch.

This does not help blocks starting with a label, as they are
reached via a taken branch, and that would require saving the
complete register state at the branch.

[PULL 3/3] accel/tcg: Add CPU_LOG_EXEC tracing for cpu_io_recompile()

[Richard Henderson]

From: Peter Maydell <peter.maydell@linaro.org>

When using -icount, it's useful for the CPU_LOG_EXEC logging
to include information about when cpu_io_recompile() was
called, because it alerts the reader of the log that the
tracing of a previous TB execution may not actually
correspond to an actually executed instruction. For instance
if you're using -icount and also -singlestep then a guest
instruction that makes an IO access appears in two
"Trace" lines, once in a TB that triggers the cpu_io_recompile()
and then again in the TB that actually executes.

(This is a similar reason to why the "Stopped execution of
TB chain before..." logging in cpu_tb_exec() is helpful
when trying to track execution flow in the logs.)

Igor2 reported on IRC that this seems to cause a crash when
using an hppa guest. This is apparently happening on a proprietary
disk image, so no reproducible test case, but the logging of
the tail end of -d in_asm,op is at:
 http://igor2.repo.hu/tmp/in_asm_op.log

QEMU asserts with
../tcg/tcg.c:3346: tcg fatal error

The TB in question involves several conditional branches; the
generated TCG ops look OK to me, and reverting the two commits
b4cb76e6208cf6b5b and cd0372c515c4732d8b fixes the crash.
(We didn't test reverting only one of the two commits separately.)
