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.

The arguments to tcg_gen_helper32 for these functions were not
updated correctly in rev 2bece2c88331f024a46527634e3dd91c71d22141.
