Amend r138129 (reduction of SLocEntries) which introduced performance regression due
to increased calls to SourceManager::getFileID. (rdar://9992664)

Use a slightly different approach that is more efficient both in terms of speed
(no extra getFileID calls) and in SLocEntries reduction.

Comparing pre-r138129 and this patch we get:

For compiling SemaExpr.cpp reduction of SLocEntries by 26%.
For the boost enum library:
-SLocEntries -34% (note that this was -5% for r138129)
-Memory consumption -50%
-PCH size -31%

Reduced SLocEntries also benefit the hot function SourceManager::getFileID,
evident by the reduced "FileID scans".

Boost the efficiency of SourceManager::getMacroArgExpandedLocation.

Currently getMacroArgExpandedLocation is very inefficient and for the case
of a location pointing at the main file it will end up checking almost all of
the SLocEntries. Make it faster:

-Use a map of macro argument chunks to their expanded source location. The map
is for a single source file, it's stored in the file's ContentCache and lazily
computed, like the source lines cache.
-In SLocEntry's FileInfo add an 'unsigned NumCreatedFIDs' field that keeps track
of the number of FileIDs (files and macros) that were created during preprocessing
of that particular file SLocEntry. This is useful when computing the macro argument
map in skipping included files while scanning for macro arg FileIDs that lexed from
a specific source file. Due to padding, the new field does not increase the size
of SLocEntry.

Introduce SourceManager::getMacroArgExpandedLocation function.

If we pass it a source location that points inside a function macro argument,
the returned location will be the macro location in which the argument was expanded.
If a macro argument is used multiple times, the expanded location will
be at the first expansion of the argument.
e.g.
MY_MACRO(foo);
^
Passing a file location pointing at 'foo', will yield a macro location
where 'foo' was expanded into.

Make SourceManager::getLocation call getMacroArgExpandedLocation as well.
