tcg/arm: Remove unused tcg_out_addi()

Remove the unused function tcg_out_addi() from the ARM TCG backend;
this fixes a compilation failure on ARM hosts with newer gcc.

tcg: Don't declare TCG_TARGET_REG_BITS in tcg-target.h

It is now declared for all tcg targets in tcg.h,
so the tcg target specific declarations are redundant.

tcg: Always define all of the TCGOpcode enum members.

By always defining these symbols, we can eliminate a lot of ifdefs.

To allow this to be checked reliably, the semantics of the
TCG_TARGET_HAS_* macros must be changed from def/undef to true/false.
This allows even more ifdefs to be removed, converting them into...

Delegate setup of TCG temporaries to targets

Delegate TCG temp_buf setup to targets, so that they can use a stack
frame later instead.

cpu-exec.c: avoid AREG0 use

Make functions take a parameter for CPUState instead of relying
on global env. Pass CPUState pointer to TCG prologue, which moves
it to AREG0.

Thanks to Peter Maydell and Laurent Desnogues for the ARM prologue
change.

Revert the hacks to avoid AREG0 use on Sparc hosts....

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 arm/mips/ia64: add a comment about retranslation and caches

Add a comment about cache coherency and retranslation, so that people
developping new targets based on existing ones are warned of the issue.

tcg/arm: improve constant loading

Improve constant loading in two ways:
- On all ARM versions, it's possible to load 0xffffff00 = 0x100 using
the mvn rd, #0. Fix the conditions.
 On <= ARMv6 versions, where movw and movt are not available, load the
constants using mov and orr with rotations depending on the constant...
