[NFC][X86][AArch64] Add 'A - (A & B)' pattern tests (PR44448)

The fold 'A - (A & (B - 1))' -> 'A & (0 - B)'
added in 8dab0a4a
is too specific. It should just be 'A - (A & B)' -> 'A & (~B)'

Name: X - (X & Y)  ->  X & (~Y)
%o = and i32 %X, %Y
%r = sub i32 %X, %o
  =>
%n = xor i32 %Y, -1
%r = and i32 %X, %n
