Reinstate r284008 reverted in r284081, with two fixes:
1) Merge and demote variable definitions when we find a redefinition in
MergeVarDecls, not only when we find one in AddInitializerToDecl (we only reach
the second case if it's the addition of the initializer itself that converts an
existing declaration into a definition).
2) When rebuilding a redeclaration chain for a variable, if we merge two
definitions together, mark the definitions as merged so the retained definition
is made visible whenever the demoted definition would have been.
Original commit message (from r283882):

[PPC] Shorter sequence to load 64bit constant with same hi/lo words
This is a patch to implement pr30640.
When a 64bit constant has the same hi/lo words, we can use rldimi to copy the low word into high word of the same register.
This optimization caused failure of test case bperm.ll because of not optimal heuristic in function SelectAndParts64. It chooses AND or ROTATE to extract bit groups from a register, and OR them together. This optimization lowers the cost of loading 64bit constant mask used in AND method, and causes different code sequence. But actually ROTATE method is better in this test case. The reason is in ROTATE method the final OR operation can be avoided since rldimi can insert the rotated bits into target register directly. So this patch also enhances SelectAndParts64 to prefer ROTATE method when the two methods have same cost and there are multiple bit groups need to be ORed together.

Disable Modules when building the libc++ sources.
Libc++ will not build with modules enabled. In order to support an in-tree
libc++ when LLVM_ENABLE_MODULES is ON we need to explicitly disable the feature.
Unfortunately the libc++ sources are fundamentally non-modular. For example
iostream.cpp defines cout, cerr, wout, ... as char buffers instead of streams
in order to better control initialization/destruction. Not shockingly Clang
diagnoses this. Many other sources files define _LIBCPP_BUILDING_FOO macros to
provide definitions for normally inline symbols (See bind.cpp). Finally The
current module.map prohibits using <strstream> in C++11 so we can't build

The following patch is for compatability with Microsoft.
Microsoft ignores the keyword "short" when used after a jmp, for example:
__asm {
jmp short label
label:

A test for that patch will be added in another patch, since it's located in clang's codegen tests. Link will be added shortly.
