Andrea Di Biagio a34cab9be7 [InstCombine] Fix wrong folding of constant comparison involving ahsr and negative quantities (PR20945).
Example:
define i1 @foo(i32 %a) {
  %shr = ashr i32 -9, %a
  %cmp = icmp ne i32 %shr, -5
  ret i1 %cmp
}

Before this fix, the instruction combiner wrongly thought that %shr
could have never been equal to -5. Therefore, %cmp was always folded to 'true'.
However, when %a is equal to 1, then %cmp evaluates to 'false'. Therefore,
in this example, it is not valid to fold %cmp to 'true'.
The problem was only affecting the case where the comparison was between
negative quantities where one of the quantities was obtained from arithmetic
shift of a negative constant.

This patch fixes the problem with the wrong folding (fixes PR20945).
With this patch, the 'icmp' from the example is now simplified to a
comparison between %a and 1. This still allows us to get rid of the arithmetic
shift (%shr).
