tcg: Add TCGV_UNUSED_PTR, TCGV_IS_UNUSED_PTR, TCGV_EQUAL_PTR

We have macros for marking TCGv values as unused, checking if they
are unused and comparing them to each other. However these only exist
for TCGv_i32 and TCGv_i64; add them for TCGv_ptr as well....

tcg/s390: Remove sigill_handler

Commit c9baa30f42a87f61627391698f63fa4d1566d9d8 failed to
delete all of the relevant code, leading to Werrors about
unused symbols.

TCG: Fix I64-on-32bit-host temporaries

We have cache pools of temporaries that we can reuse later when they've
already been allocated before.

These cache pools differenciate between the target TCG variable type they
contain. So we have one pool for I32 and one pool for I64 variables....

tcg/i386: cleanup useless #ifdef

TCG_TARGET_HAS_movcond_i32 is always defined to 1 in tcg-target.h, so
remove the corresponding #ifdef #endif sequence, left from a previous
refactoring.

tcg/i386: use movbe instruction in qemu_ldst routines

The movbe instruction has been added on some Intel Atom CPUs and on
recent Intel Haswell CPUs. It allows to load/store a value and at the
same time bswap it.

This patch detects the avaibility of this instruction and when available...

tcg/i386: add support for three-byte opcodes

Add support for three-byte opcodes, starting with the 0x0f 0x38 prefix.
Use P_EXT38 as the new constant, and shift all other constants so that
P_EXT and P_EXT38 have neighbouring values.

tcg/i386: remove hardcoded P_REXW value

P_REXW is defined has a constant at the beginning of i386/tcg-target.c,
but the corresponding bit is later used in a harcoded way, which defeat
the purpose of a constant.

Fix that by using a conditional expression operator instead of a shift....

tcg/i386: fix a comment

tcg: Use bitmaps for free temporaries

We previously allocated 32-bits per temp for the next_free_temp entry.
We now allocate 4 bits per temp across the 4 bitmaps.

Using a linked list meant that if a translator is tweeked, resulting in
temps being freed in a different order, that would have follow-on effects...
