Following the discussion on D22038, this refactors a PowerPC specific setcc -> srl(ctlz) transformation so it can be used by other targets.

Summary:
The assembler currently does not check the branch target for CBZ/CBNZ
instructions, which only permit branching forwards with a positive offset. This
adds validation for the branch target to ensure negative PC-relative offsets are
not encoded into the instruction, whether specified as a literal or as an
assembler symbol.

Summary:
Multiple APIs were taking a StringMap for the ImportLists containing
the entries for for all the modules while operating on a single entry
for the current module. Instead we can pass the desired ModuleImport
directly. Also some of the APIs were not const, I believe just to be
able to use operator[] on the StringMap.

Recall that MSVC always gives enums the type 'int', nothing else. MSVC
2015 does not appear to have this problem anymore.
Clang-cl -Wmicrosoft-enum-value flags this, FWIW, so now I have a true
positive for my warning. :)

Summary:
Fixed a bug in ThinLTOCodeGenerator's temp file dumping. The Twine
needs to be passed directly as an argument, or a copy saved into a
std::string.
It doesn't seem there are any consumers of this, so I added a new option
to llvm-lto to enable saving of temp files during ThinLTO, and augmented
a test to use it to check post-import but pre-opt bitcode.

This was indented really awkwardly, and clang-format didn't seem to
know how to do any better. Avoid the issue with a temporary variable.

Summary: This is similiar to r278752, where I found that the std::iterator<...> base can be normal.

Remove -disable-inlining flag that snuck into the test I added for r278739.
It doesn't have an effect in ThinLTO mode (something that should be fixed),
but in any case the checks depend on inlining currently.

Summary:
thinLTOResolveWeakForLinkerModule needs to drop any preempted weak symbols
that were converted to available_externally from comdats, otherwise we
will get a verification failure (since available_externally is a
declaration for the linker, and no declarations can be in a comdat).
