As per dotnet/coreclr#20788 (comment), we are currently generating some inefficient code for certain op and comparison scenarios.

For example, on if ((xbits ^ ybits) < 0), we are currently generating:

xor      edx, eax
test     edx, edx
jge      SHORT G_M7953_IG04

When we could get rid of the test and just generate:

xor edx, eax
jns SHORT G_M7953_IG04
