[InstCombine] Make x86 PADDS/PSUBS constant folding tests generic 

As discussed on D55894, this replaces the existing PADDS/PSUBUS intrinsics with the the sadd/ssub.sat generic intrinsics and moves the tests out of the x86 subfolder.

PR40110 has been raised to fix the regression with constant folding vectors containing undef elements.
