gollvm: sync with llvm trunks and update llvm repository

LLVM trunk 1b2842bf902a CreateMemSet use MaybeAlign.
LLVM trunk 1dfede3122ee move CodeGenFileType enum to Support/CodeGen.h.

Add a few missing included header files to Gollvm:
1, Add header file "llvm/Support/CommandLine.h" to file passes/GC.cpp.
2, Add header file "llvm/InitializePasses.h" to files passes/GoNilChecks.cpp and
   passes/GoStatepoints.cpp.

LLVM project is moving to Github, the LLVM sub-project repository
"http://llvm.org/git/llvm.git" is now not maintained, and we can't download the
latest LLVM code from it, see https://llvm.org/docs/Proposals/GitHubMove.html.
So this CL updates the README document.

In addition, CL 210323 introduces a build error: on a platform that does not
support "-fsplit-stack", cmake will still report an error message even if
GOLLVM_USE_SPLIT_STACK is turned off. This CL also fixed the error.
