DirectoryLookup::DirType into SourceManager.h

to whether the fileid is a 'extern c system header' in addition to whether it
is a system header, most of this is spreading plumbing around.  Once we have that,
PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to
base the system header state on FileIDInfo instead of HeaderSearch.  Finally,
in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness
of a file being entered can be set due to the #includer or the #includee.

* Move FormatError() from TextDiagnostic up to DiagClient, remove now  
  empty class TextDiagnostic
* Make DiagClient optional for Diagnostic

This fixes the following problems:

* -html-diags (and probably others) does now output the same set of  
  warnings as console clang does
* nothing crashes if one forgets to call setHeaderSearch() on  
  TextDiagnostic
* some code duplication is removed

The new MemoryBuffer doesn't "leak" file descriptors and handles the
small file case efficiently.

llvm-svn: 49032

This is a temporary solution to avoid running out of file descriptors (which defaults to 256).

Need to benchmark to understand the speed benefit. If the benefit is small, the simple solution is to avoid memory mapping files. If the benefit is significant, more thought is necessary.

lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.

deserialization.  Eventually this should be replaced with a lazy-reading
mechanism that only reads source files when they are needed by clients.

Now sourcemanager deserializer automatically self-registers itself with
the deserializer.

whether the location is the start and/or end of an expansion.
These are currently not set or used by anything.

Disabled assignments for ContentCache.
Copy-ctor for ContentCache now has an assertion preventing it to
be copied from an object that already has an allocated buffer.

llvm-svn: 43526

single class: ContentCache.  This simplifies the logic in
SourceManager and makes the ownership of MemoryBuffers clearer.

with x's for now.  The APIs are all unimplemented, so it doesn't do 
anything yet! :)

Removed clang solution file for VC++, which didn't work properly because of hard coded paths in the llvm project files.
Changed windows detection to use LLVM pp constant.

This is important in insane cases like the one dannyb sent me recently:

#define F0(a) void a(){}
#define F1(a) F0(a##0) F0(a##1) F0(a##2) F0(a##3) F0(a##4) F0(a##5) F0(a##6) F0(a##7)
#define F2(a) F1(a##0) F1(a##1) F1(a##2) F1(a##3) F1(a##4) F1(a##5) F1(a##6) F1(a##7)
#define F3(a) F2(a##0) F2(a##1) F2(a##2) F2(a##3) F2(a##4) F2(a##5) F2(a##6) F2(a##7)
#define F4(a) F3(a##0) F3(a##1) F3(a##2) F3(a##3) F3(a##4) F3(a##5) F3(a##6) F3(a##7)
#define F5(a) F4(a##0) F4(a##1) F4(a##2) F4(a##3) F4(a##4) F4(a##5) F4(a##6) F4(a##7)

This speeds up -E on xalancbmk by 2.4%

llvm-svn: 40461

llvm-svn: 40460

bottleneck for -E computation, because every token that starts a line needs
to determine *which* line it is on (so -E mode can insert the appropriate 
vertical whitespace).  This optimization improves this common case where
it is striding through the line # table.

This speeds up -E on xalancbmk by 3.2%

keeps the MacroInfo table more compact.

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

llvm-svn: 40108

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.
