It was really hard to tell that modules are experimental. This makes it
really clear by
* Noting the experimental status in the title.
* Moving the "warning" above the table of contents.

Half the internet has wildly incorrect ideas about what LLVM is (in
particular, many get the impression that LLVM is some magical
cross-platform runtime), so saying "LLVM" near "cross-compilation" in a
user-facing doc might provoke confusion.

Last I heard LSan is getting close to prime-time, but for now keep
LeakSanitizer.rst hidden (especially since it contains so little
content).

There are more than one paths to where the frame information is emitted. Place
the call to generateCompactUnwindEncodings() into the method which outputs the
frame information, thus ensuring that the encoding is there for every path. This
involved threading the MCAsmBackend object through to this method.

In DIBuilder, the context field of a TAG_member is updated to use the
scope reference. Verifier is updated accordingly.
DebugInfoFinder now needs to generate a type identifier map to have
access to the actual scope. Same applies for BreakpointPrinter.
processModule of DebugInfoFinder is called during initialization phase
of the verifier to make sure the type identifier map is constructed early
enough.
We are now able to unique a simple class as demonstrated by the added
testing case.

DIScope::getContext is a wrapper function that calls the specific getContext
method on each subclass. When we switch DIType::getContext to return DIScopeRef
instead of DIScope, DIScope::getContext can no longer return a DIScope without
a type identifier map.
DIScope::getContext is only used by DwarfDebug, so we move it to DwarfDebug
to have easy access to the type identifier map.

The work on this project was left in an unfinished and inconsistent state.
Hopefully someone will eventually get a chance to implement this feature, but
in the meantime, it is better to put things back the way the were. I have
left support in the bitcode reader to handle the case-range bitcode format,
so that we do not lose bitcode compatibility with the llvm 3.3 release.

This helper function needs the type identifier map when we switch
DIType::getContext to return DIScopeRef instead of DIScope.
Since isSubprogramContext is used by DwarfDebug only, We move it to DwarfDebug
to have easy access to the map.

Apparently folks run into this (PR17097). The flag is not supported by
MSVC either, but we should parse it so we don't get confused when it occurs.
This changes the clang-cl output for "clang-cl /c /o foo.obj" from:
clang-cl.exe: error: no such file or directory: '/o'
clang-cl.exe: error: no such file or directory: 'foo.obj'
to:
clang-cl.exe: warning: argument unused during compilation: '/o bajs.obj'

A reference to a scope is more general than a reference to a type since
DIType is a subclass of DIScope.
A reference to a type can be either an identifier for the type or
the DIType itself, while a reference to a scope can be either an
identifier for the type (when the scope is indeed a type) or the
DIScope itself. A reference to a type and a reference to a scope
will be resolved in the same way. The only difference is in the
verifier when a field is a reference to a type (i.e. the containing
type field of a DICompositeType) or a field is a reference to a scope
(i.e. the context field of a DIType).
This is to get ready for switching DIType::getContext to return
DIScopeRef instead of DIScope.
Tighten up isTypeRef and isScopeRef to make sure the identifier is not
empty and the MDNode is DIType for TypeRef and DIScope for ScopeRef.

it is an implicit instantiation of a class template specialization), pick the
first-loaded definition to be the canonical definition, and merge all other
definitions into it.
This is still rather incomplete -- we need to extend every form of declaration
that can appear within a CXXRecordDecl to be redeclarable if it came from an
AST file (this includes fields, enumerators, ...).

Fix XCoreLowerThreadLocal trying to initialise globals

Add handling of const expressions containing thread local variables.
These need to be replaced with instructions, as the thread ID is
