Sanjay Patel ad6c7a9c3a [InstCombine] don't change the size of a select if it would mismatch its condition operands' sizes 
Don't always:
cast (select (cmp x, y), z, C) --> select (cmp x, y), (cast z), C'

This is something that came up as far back as D26556, and I lost track of it. 
I suspect that this transform is part of the underlying problem that is 
inspiring some of the recent proposals that seek to match larger patterns 
that include a cast op. Even if that's not true, this transform causes
problems for codegen (particularly with vector types).

A transform to actively match the size of cmp and select operand sizes should
follow. This patch just removes the harmful canonicalization in the other
direction.

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.
