[InstCombine] Allow InstCombine to merge adjacent guards
Summary:
If there are two adjacent guards with different conditions, we can
remove one of them and include its condition into the condition of
another one. This patch allows InstCombine to merge them by the
following pattern:
guard(a); guard(b) -> guard(a & b).
