Pirama Arumuga Nainar 011eaae1ea [DAGCombiner] Do not fold truncate(build_vector(..)) if it creates an illegal type 
Summary:
It can be the case that a vector type is legal but the corresponding
scalar type is not legal for an architecture (i8 vs. v16i8 on AArch64).
Check if the scalar type created when folding
  truncate(build_vector(x,y)) -> build_vector(truncate(x),truncate(y))

is legal if we are running after the type legalizer.

This fixes https://github.com/android/ndk/issues/1207.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

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.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
