tcg: Remove redundant declarations of TCG_TARGET_REG_BITS

tcg: Standardize on TCGReg as the enum for hard registers

Most targets did not name the enum; tci used TCGRegister.

tcg-i386: Introduce limited deposit support

x86 cannot provide an optimized generic deposit implementation. But at
least for a few special cases, namely for writing bits 0..7, 8..15, and
0..15, versions using only a single instruction are feasible.
Introducing such limited support improves emulating 16-bit x86 code on...

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...

TCG/x86: use stack for TCG temps

Use stack instead of temp_buf array in CPUState for TCG
temps.

TCG/x86: use TCG_REG_CALL_STACK instead of TCG_REG_ESP

Except for specific cases where the use of %esp changes the encoding of
the instruction, it's cleaner to use TCG_REG_CALL_STACK instead of
TCG_REG_ESP.

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....
