tcg/s390: Remove unused tcg_out_addi()

Remove the unused function tcg_out_addi() from the s390 TCG backend;
this brings it into line with other backends.

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: Optionally sign-extend 32-bit arguments for 64-bit hosts.

Some hosts (amd64, ia64) have an ABI that ignores the high bits
of the 64-bit register when passing 32-bit arguments. Others
require the value to be properly sign-extended for the type.
I.e. "int32_t" must be sign-extended and "uint32_t" must be...

tcg-s390: Icache flush is a no-op.

Before gcc 4.2, builtin_clear_cache doesn't exist, and
afterward the gcc s390 backend implements it as nothing.
