Most of the test changes are trivial instruction reorderings and differing
register allocations, without any obvious performance impact.

The patch fixed the issue that RV64 didn't clear the upper bits
when return complex floating value with lp64 ABI.
float _Complex
complex_add(float _Complex a, float _Complex b)
{
return a + b;
}
RealResult = zero_extend(RealA + RealB)
ImageResult = ImageA + ImageB
Return (RealResult | (ImageResult << 32))
The patch introduces shouldExtendTypeInLibCall target hook to suppress
the AssertZext generation when lowering floating LibCall.

This follows similar logic in the ARM and Mips backends, and allows the free
use of s0 in functions without a dedicated frame pointer. The changes in
callee-saved-gprs.ll most clearly show the effect of this patch.

These are closely modeled on similar tests for the ilp32 ABI. Like those
tests, we group together tests that should be common cross lp64, lp64+lp64f,
and lp64+lp64f+lp64d ABIs.
