NestedMacroInstantiations -> NestedMacroExpansions.
With this change, libclang should be completely converted except for
uses of SourceManger and SourceLocation APIs, and the C bindings for
those APIs.

During type legalization we often use the SIGN_EXTEND_INREG SDNode.
When this SDNode is legalized during the LegalizeVector phase, it is
scalarized because non-simple types are automatically marked to be expanded.
In this patch we add support for lowering SIGN_EXTEND_INREG manually.
This fixes CodeGen/X86/vec_sext.ll when running with the '-promote-elements'
flag.

This is switches all the interfaces points (and most of the commenst
/ local variables I saw on my way through) regarding the
NestedMacroInstantiations bit.
The libclang enums corresponding to this state were renamed, but
a legacy enum was added with the old name, and the same value to keep
existing clients working. I've added a documentation blurb for it, but
let me know if there is a canonical way to document legacy elemenst of
the libclang interface.
No functionality changed here, even in tests.

MacroInstantiation -> MacroExpansion rename. Internally, everything is
switched.
Introduce a new cursor kind enum with the new name, but retain the old
name as an alias so that we don't break backwards compatibility.
Also update the debug printing routine to use 'macro expansions' as its
explicitly not guaranteed to be stable, and mechanically switch the test
cases over to that.

variants to 'expand'. This changed a couple of public APIs, including
one public type "MacroInstantiation" which is now "MacroExpansion". The
rest of the codebase was updated to reflect this, especially the
libclang code. Two of the C++ (and thus easily changed) libclang APIs
were updated as well because they pertained directly to the old
MacroInstantiation class.
No functionality changed.

'expand'. Also update the public API it provides to the new term, and
propagate that update to the various clients.
No functionality changed.

and 'expansions' rather than 'instantiated' and 'contexts'.
This is the first of several patches migrating Clang's terminology
surrounding macros from 'instantiation' to 'expansion'.

TargetAsmInfo, which in turn pulls in TargetRegisterInfo, etc. :-( There are
other cases of violations, but this is probably the worst.
This patch is but one small step towards fixing this. 500 more steps to go. :-(

Original commit message:
Count references to interference cache entries.
Each InterferenceCache::Cursor instance references a cache entry. A
non-zero reference count guarantees that the entry won't be reused for a
new register.
This makes it possible to have multiple live cursors examining
interference for different physregs.
The total number of live cursors into a cache must be kept below
InterferenceCache::getMaxCursors().
Code generation should be unaffected by this change, and it doesn't seem
to affect the cache replacement strategy either.
