David Majnemer 4fc6a8e406 [Target] Don't return a std::string in getRegAsmName 
getRegAsmName ends up making a copy of the register's name in order to
make a lower-case version of it.  This is bad because
getRegForInlineAsmConstraint, it's sole caller, does a lowercase
comparison anyway.

This resulted in a significant regression in compile time for the Linux
kernel because getRegAsmName is called in a loop by
getRegForInlineAsmConstraint.

Instead, forgo the call to lower in getRegAsmName and have it return a
StringRef.

No functionality change is intended.

Low Level Virtual Machine (LLVM)
================================

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

LLVM is open source software. You may freely distribute it under the terms of
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.
