tcg: If DEBUG_TCGV, distinguish TCGv_ptr from TCGv_i32/TCGv_i64

When compiling with DEBUG_TCGV enabled, make the TCGv_ptr type distinct
from TCGv_i32/TCGv_i64. This means that using an i32 or i64 TCG op to
manipulate a TCGv_ptr will always be detected at compile time, rather...

tcg/tcg-op.h: Fix prototypes for ld/st functions on 64 bit hosts

The prototypes for the ld/st functions on a 64 bit host declared
the address parameter as a TCGv_i64 rather than a TCGv_ptr. This
worked OK (since the two are aliases), but needs to be fixed to...

Use the correct header in the TCG MIPS code to find cacheflush() on OpenBSD.

Use the correct header in the TCG MIPS code to find cacheflush() on OpenBSD
to fix compilation of the MIPS host support for OpenBSD/mips64 based architecures.

tcg: don't keep dead outputs in registers

If an op with dead outputs is not removed, because it has side effects
or has multiple output and only one dead, mark the registers as dead
instead of saving them. This avoid a few register spills on TCG targets
with low register count, especially with div2 and mul2 ops, or when a...

tcg: mark dead output argument in op_dead_args

If an op is not removed and has dead output arguments, mark it
in op_dead_args similarly to what is done for input arguments.

tcg: replace op_dead_iargs by op_dead_args

Allow all args to be dead by replacing the input specific op_dead_iargs
variable by op_dead_args. Note this is a purely mechanical change.

tcg/arm: Support host code being compiled for Thumb

Although the TCG generated code is always in ARM mode, it is possible
that the host code was compiled by gcc in Thumb mode (this is often the
default for Linux distributions targeting ARM v7 only). Handle this...

tcg: Add support for debugging leakage of temporaries

Add support (if CONFIG_DEBUG_TCG is defined) for debugging leakage
of temporary variables. Generally any temporaries created by
a target while it is translating an instruction should be freed
by the end of that instruction; otherwise carefully crafted...
