This patch adds ObjectFilePCHContainerOperations uses the LLVM backend
to put the contents of a PCH into a __clangast section inside a COFF, ELF,
or Mach-O object file container.
This is done to facilitate module debugging by makeing it possible to
store the debug info for the types defined by a module alongside the AST.

This is a necessary prerequisite for debugging with modules.
The .pcm files become containers that hold the serialized AST which allows
us to store debug information in the module file that can be shared by all
object files that were built importing the module.
This reapplies r230044 with a fixed configure+make build and updated
dependencies and testcase requirements. Over the last iteration this
version adds
- missing target requirements for testcases that specify an x86 triple,
- a missing clangCodeGen.a dependency to libClang.a in the make build.

Various tests had sprung up over the years which had --check-prefix=ABC on the
RUN line, but "CHECK-ABC:" later on. This happened to work before, but was
strictly incorrect. FileCheck is getting stricter soon though.

increasingly prevailing case to the point that new features
like ARC don't even support the fragile ABI anymore.
This required a little bit of reshuffling with exceptions
because a check was assuming that ObjCNonFragileABI was
only being set in ObjC mode, and that's actually a bit
obnoxious to do.
Most, though, it involved a perl script to translate a ton
of test cases.
Mostly no functionality change for driver users, although
there are corner cases with disabling language-specific
exceptions that we should handle more correctly now.

interest (e.g., as used by clang_getCursor()), count the
decl-specifier-seq as part of the source range, as we do for
clang_annotateTokens(). Makes clang_getCursor() work properly for the
result types of functions, for example.

to an "overloaded" set of declarations. This cursor kind works for
unresolved references to functions/templates (e.g., a call within a
template), using declarations, and Objective-C class and protocol
forward declarations.

region of interest (if provided). Implement clang_getCursor() in terms
of this traversal rather than using the Index library; the unified
cursor visitor is more complete, and will be The Way Forward.
Minor other tweaks needed to make this work:
- Extend Preprocessor::getLocForEndOfToken() to accept an offset
from the end, making it easy to move to the last character in the
token (rather than just past the end of the token).
- In Lexer::MeasureTokenLength(), the length of whitespace is zero.

statements, moving some of the more unnatural kinds of references
(VarRef, EnumConstantRef, etc.) over to the expressions. We can now
poke at arbitrary expressions and statements with, e.g.,
clang_getCursor() and get back useful information (e.g., source
ranges).

API. This is a catch-all for any declaration known to Clang but not
specifically part of the CIndex API. We'll use the same approach with
expressions, statements, references, etc., as needed.

CIndex functions that (1) map from a reference or declaration to the
corresponding definition, if available, and (2) determine whether a
given declaration cursor is also a definition. This eliminates a lot
of duplication in the cursor kinds, and maps more closely to the Clang
ASTs.
This is another API + ABI breaker with no deprecation. Yay, progress.

in CXCursor.cpp. With this sane representation, fix the class
reference that is part of Objective-C category declarations so that
the cursor's location matches up with the reference, not the class
being referred to.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
