Wei Mi 158f898c51 Remove the restriction that MachineSinking is now stopped by "insert_subreg, 
subreg_to_reg, and reg_sequence" instructions.

This is to solve PR28852. The restriction was added at 2010 to make better register
coalescing. We assumed that it was not necessary any more. Testing results on x86
supported the assumption.

We will look closely to any performance impact it will bring and will be prepared
to help analyzing performance problem found on other architectures.

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.
