[cmake] Move the including of utils/unittests under LLVM_INCLUDE_UTILS instead of LLVM_INCLUDE_TESTS.
This does not change anything by default since LLVM_INCLUDE_UTILS is already set

the only way that this can cause changes is in the case where LLVM_INCLUDE_UTILS
is set to TRUE, but LLVM_INCLUDE_TESTS is FALSE. In that case, building gtest is
not a huge cost.
The reason to do this is that without this change, one can not turn off
LLVM_INCLUDE_TESTS in downstream projects that also use gtest for unittests. It
also just in general makes more sense since LLVM_INCLUDE_UTILS gates FileCheck
and other utilities that are along the lines of gtest.

Fix MSVC 2015 compilation failure around range-for without curly braces
It doesn't appear to like this pattern:
for (auto X : Xs)
if (...) { ... }
else ...;
We have heard anecdotes that range based for loops are implemented as a
token rewrite in MSVC's lexer, and that the most challenging part of the
rewrite is finding the end of the for loop. That makes sense, given that
it's a lexer.

[X86][SSE] Allow folding of store/zext with PEXTRW of 0'th element
Under normal circumstances we prefer the higher performance MOVD to extract the 0'th element of a v8i16 vector instead of PEXTRW.
But as detailed on PR27265, this prevents the SSE41 implementation of PEXTRW from folding the store of the 0'th element. Additionally it prevents us from making use of the fact that the (SSE2) reg-reg version of PEXTRW implicitly zero-extends the i16 element to the i32/i64 destination register.
This patch only preferentially lowers to MOVD if we will not be zero-extending the extracted i16, nor prevent a store from being folded (on SSSE41).
Fix for PR27265.

Unify process launching code on linux
Summary:
We've had two copies of code for launching processes:
- one in NativeProcessLinux, used for launching debugged processes
- one in ProcessLauncherAndroid, used on android for launching all other kinds of processes
These have over time acquired support for various launch options, but neither supported all of
them. I now replace them with a single implementation ProcessLauncherLinux, which supports all
the options the individual versions supported and set it to be used to launch all processes on
linux.
This also works around the ETXTBSY issue on android when the process is started from the platform
instance, as that used to go through the version which did not contain the workaround.
