[X86] Update handling in CGBuiltin to be tolerant of out of range immediates.

D48464 contains changes that will loosen some of the range checks in SemaChecking to a DefaultError warning that can be disabled.

This patch adds explicit masking to avoid using the upper bits of immediates to gracefully handle the warning being disabled.
