Craig Topper 03d8600380 [X86] Prevent several calls to ISD::isConstantSplatVector from returning a narrower APInt than the original scalar type 
ISD::isConstantSplatVector can shrink to the smallest splat width. But we don't check the size of the resulting APInt at all. This can cause us to misinterpret the results.

This patch just adds a flag to prevent the APInt from changing width.

Fixes PR34271.
