[PATCH] Fix PR18054

[Michael Liao]

Hi All,

The attached patch fixed PR18054 which is caused by a bug in X86
sign_extend_inreg lowering. Extra checking the in-reg type is needed as
(vsext x) is only when x is a vector type of i8, i16, or i32. If x is a
vector type of i1, is not valid to use (vsext x) alone.

Thanks for review
- Michael
