840f58617b 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.

25c4d9cc84 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
C if statements.

2bece2c883 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
zero-extended to 64-bits.

To effect this, extend the "sizemask" parameter to tcg_gen_callN
to include the signedness of the type of each parameter.  If the
tcg target requires it, extend each 32-bit argument into a 64-bit
temp and pass that to the function call.

This ABI feature is required by sparc64, ppc64 and s390x.

be6551b1e7 tcg-sparc: Implement not.
The fallback implementation of "ret = arg1 ^ -1" isn't ideal
because of the extra tcg op to load the minus one.

4b5a85c175 tcg-sparc: Implement neg.
The fallback implementation of "ret = 0 - arg1" isn't ideal,
first because of the extra tcg op to load the zero, and second
because we fail to handle zero as %g0 for arg1 of the sub.

cc6dfecf02 tcg-sparc: Implement ext32[su]_i64
The 32-bit right-shift instructions is defined to extend the shifted
output to 64-bits.  A shift count of zero therefore is a simple
extension without actually shifting.

583d121520 tcg-sparc: Implement division properly.
The {div,divu}2 opcodes are intended for systems for which the
division instruction produces both quotient and remainder.  Sparc
is not such a system.  Indeed, the remainder must be computed as

  quot = a / b
  rem = a - (quot * b)

Split out a tcg_out_div32 function that properly initializes Y
with the extension of the input to 64-bits.  Discard the code
that used the 64-bit DIVX on sparc9/sparcv8plus without extending
the inputs to 64-bits.  Implement remainders in terms of division
followed by multiplication.
