preprocessing 483.xalancbmk by about 10%, reducing the number
of file lookup queries from 2139411 to 199466 (over 10x)

// foo
// bar
// baz
we'd get two levels of call (bcpl & whitespace) for each line, leading to some
seriously deep stacks in some cases.

fileid's and macroid's across files. Clearing between files keeps the tables
smaller and slightly speeds up compilation.

redefinition of a macro could cause invalid memory to be deleted.

a bit nicer for people who pass lots of extra arguments to calls by
selecting them all instead of just the first one:
arg-duplicate.c:13:13: error: too many arguments to function
f3 (1, 1, 2, 3, 4); // expected-error {{too many arguments to function}}
^~~~~~~
This implements test/Sema/arg-duplicate.c, thanks to Neil for pointing
out this crash.

1) fix a crash on test/Sema/default.c by making
sure that the switch scope is non-null.
2) if there is an error sema'ing a default or case stmt,
make sure to return the substmt up, so that the error
recovery code has more acurate info to continue with.

SourceManager::getInstantiationLoc. With this change, every token
expanded from a macro doesn't get its own MacroID. :)
This reduces # macro IDs in carbon.h from 16805 to 9197

Since that point is now long gone, we should rename LexerToken to
Token, as it is the only kind of token we have.

fileid/offset pair, it now contains a bit discriminating between
mapped locations and file locations. This separates the tables for
macros and files in SourceManager, and allows better separation of
concepts in the rest of the compiler. This allows us to have *many*
macro instantiations before running out of 'addressing space'.
This is also more efficient, because testing whether something is a
macro expansion is now a bit test instead of a table lookup (which
also used to require having a srcmgr around, now it doesn't).
This is fully functional, but there are several refinements and
optimizations left.

We still need to do sematic analysis (and implement initializers), however this
should complete the parsing & ast building for compound literals.

Before this commit, we crashed in ParseBinOp...
[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang -parse-ast-check compound_literal.c
SemaExpr.cpp:1298: failed assertion `(rhs != 0) && "ParseBinOp(): missing right expression"'
With this commit, we still crash in the newly added action ParseCompoundLiteral (which is progress:-)
[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang -parse-ast-check compound_literal.c
SemaExpr.cpp:478: failed assertion `(Op != 0) && "ParseCompoundLiteral(): missing expression"'
The crash go away once the actions return AST nodes. I will do this in a separate commit.

return a null type. If there is an error parsing the type, pick a new type
for error recovery purposes.

- added ocu_vector_type attribute, Sema::HandleOCUVectorTypeAttribute().
- added new AST node, OCUVectorType, a subclass of VectorType.
- added ASTContext::getOCUVectorType.
- changed ASTContext::convertToVectorType() to ASTContext::getVectorType(). This is
unrelated to extended vectors, however I was in the vicinity and it was on my todo list.
Added a FIXME to Sema::HandleVectorTypeAttribute to deal with converting complex types.
