Quite a lot of effort was spent composing and decomposing 64-bit quantities in registers, when we should just create them and leave them as one 64-bit register. Signed-off-by: NRichard Henderson <rth@twiddle.net>

The TCG targets i386 and tci needed a change of the function prototype for w64. This change is currently not needed for the other TCG targets, but it can be applied to avoid code differences.

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. Signed-off-by: NRichard Henderson <rth@twiddle.net> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

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.
