[NFC][CodeGen][X86][AArch64] Add and-const-mask + const-shift pattern tests

Unlike instcombine, we currently don't turn and+shift into shift+and.
We probably should, likely unconditionally.

While i'm adding only all-ones (potentially shifted) mask,
this obviously isn't limited to any particular mask pattern:
