Unify the way we report overflow in increment/decrement operator.
Summary:
Make sure signed overflow in "x--" is checked with
llvm.ssub.with.overflow intrinsic and is reported as:
"-2147483648 - 1 cannot be represented in type 'int'"
instead of:
"-2147483648 + -1 cannot be represented in type 'int'"
, like we do for unsigned overflow.
Test Plan: clang + compiler-rt regression test suite
