[X86] Canonicalize (x > 1) ? x : 1 -> (x >= 1) ? x : 1 for sign and unsigned...

[X86] Canonicalize (x > 1) ? x : 1 -> (x >= 1) ? x : 1 for sign and unsigned to enable the use of test instructions for the compare.

This will be further canonicalized to a compare involving 0
which will enable the use of test instructions. Either using
cmovg for signed for cmovne for unsigned.

Fixes more case for PR47049
