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: 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...

tcg: get rid of copy_size in TCGOpDef

copy_size is a left-over from the dyngen era, remove it.

tcg: Make some tcg-target.c routines static.

Both tcg_target_init and tcg_target_qemu_prologue
are unused outside of tcg.c.

tcg: Initialize the prologue after GUEST_BASE is fixed.

This will allow backends to make intelligent choices about how
to implement GUEST_BASE.

tcg: Change TCGType to an enumeration.

The TCGType name was already used consistently. Changing it
to an enumeration instead of a set of defines aids debugging.

tcg: Add consistency checks for op definitions

When compiled with CONFIG_DEBUG_TCG, this code looks
for missing, duplicate and wrong entries in the
op definitions.

Errors will raise an assertion at program start
(all checks are done in the initial phase)....

tcg: add tcg_invert_cond

It is very handy to have a reliable mapping of a condition to its inverse.

Add a --enable-debug-tcg option to configure

This patch allows DEBUG_TCGV to be defined (and also prevents NDEBUG
from being defined) when passing an option to the configure script.
This should help to prevent any accidental changes that enable
DEBUG_TCGV in tcg/tcg.h from being committed in future, and may...

tcg: add a CONST flag to TCG helpers

A const function only reads its arguments and does not use TCG
globals variables. Hence a call to such a function does not
save TCG globals variabes back to their canonical location.

Fix tcg after commit 6800

The introduction of TCGV_EQUAL and not op is slightly broken.
The definition of DEBUG_TCGV shows that.

TCG: remove obsolete old_op_count profiler field

Since we don't generate any "old op" anymore, the old_op_count

Remove all traces of powerpc

According to $GCC/gcc/config/rs6000/rs6000-c.c _ARCH_PPC is the
ubiquitous define which should be used to test whether gcc targets
PowerPC, on 64bit platforms _ARCH_PPC64 will be also defined.

- no need to generate a log of dyngen ops generated...

Some fixes for TCG debugging

This fixes a few things after Paul's improvements for TCG debugging:

- change TCGv_i64 field name to something different from
    TCGv_i32
  - fix things in tcg that the above change made visible.
