	* longlong.h: Merge in changes from glibc.
	Also don't clobber %g2 register in 32bit SPARC assembly, so that
	-mno-app-regs libgcc can be compiled.

	can be used in libgcc2.a. Also, make sure on most architectures
	(at least on all which have optimized code in longlong.h defined
	for) {SI,W}_TYPE_SIZE is suitable for preprocessor tests.
