f96b006367 Add new RegionInfo pass.
The RegionInfo pass detects single entry single exit regions in a function,
where a region is defined as any subgraph that is connected to the remaining
graph at only two spots.
Furthermore an hierarchical region tree is built.
Use it by calling "opt -regions analyze" or "opt -view-regions".

98cfb53af4 Added support to MachO.h for many defines and structures that are needed
to Parse mach-o files. All defines have been renamed to not conflict with
#defines in mach header files, all structures were left named the same but
are in the llvm::MachO namespace.

8be3291f59 Speculatively revert r108813, in an attempt to get the self-host buildbots working again. I don't see why this patch
would cause them to fail the way they are, but none of the other intervening patches seem likely either.

de4845c163 Switch the code generator (except the JIT) onto the new DebugLoc
representation.  This eliminates the 'DILocation' MDNodes for 
file/line/col tuples from -O0 -g codegen.

This remove the old DebugLoc class, making it a typedef for DebugLoc,
I'll rename NewDebugLoc next.

I didn't update the JIT to use the new apis, so it will continue to
work, but be as slow as before.  Someone should eventually do this
or, better yet, rip out the JIT debug info stuff and build the JIT
on top of MC.

b227925fa3 Add a new "NewDebugLoc" class which will eventually replace DebugLoc,
and will replace the 'DbgInfo' member in Instruction.

The benefit of NewDebugLoc is that it is compact (8 bytes vs 12/24 
bytes for the DbgInfo member in Instruction on a 32/64 bit system),
it means that we will end up not having to allocate MDNodes to 
represent the "DILocations" in common cases of -O0 -g, and it is
much more efficient to get things out of than the MDNode.

ec39f095f5 Fix a major source of compile-time slowness at -O0 -g by optimizing
the storage of !dbg metadata kinds in the instruction themselves.
The on-the-side hash table works great for metadata that not-all
instructions get, or for metadata that only exists when optimizing.
But when compile-time is everything, it isn't great.

I'm not super thrilled with the fact that this plops a TrackingVH in
Instruction, because it grows it by 3 words.  I'm investigating 
alternatives, but this should be a step in the right direction in any
case.

(it at all).

f0356fe140 Kill ModuleProvider and ghost linkage by inverting the relationship between
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
GlobalValues now, and doesn't provide modules, it's renamed to
"GVMaterializer". Code that used to need a ModuleProvider to materialize
Functions can now materialize the Functions directly. Functions no longer use a
magic linkage to record that they're materializable; they simply ask the
GVMaterializer.

Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
the functions that refer to it. Instead, because Module now exposes the same
functionality ModuleProvider used to, we store a Module* in any
LLVMModuleProviderRef and translate in the wrapper methods.  The bindings to
other languages still use the ModuleProvider concept.  It would probably be
worth some time to update them to follow the C++ more closely, but I don't
intend to do it.

Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735.

4813035b72 change Mangler::makeNameProper to return its result in a SmallVector
instead of returning it in an std::string.  Based on this change:

1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
   making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
   prefixes, not use temporary std::strings, and to avoid other crimes.

b5d568cc70 Provide dbgs(), a circular-buffering debug output stream. By default it
simply passes output to errs().  If -debug-buffer-size=N is set N > 0,
dbgs() buffers its output until program termination and dumps the last N
characters sent to it.  This is handy when debugging very large inputs.

e59011e7d9 Add circular_raw_ostream, which buffers its output in a circular queue
and outputs it when explicitly flushed.  The intent is to use it in
situations such as debug output logging where a signal handler can take
care of flushing the buffer at program termination.

7b1eb8a409 Remove uber-gross hack. The define _snprintf to snprintf is invalid due to two reasons: 1. Accroding to C++ standard snprintf should be available in std namespace (and __gnu_cxx in case of GCC to). Such ifdef will change all snprintf's to _snprintf's, but won't bring snprintf to all necessary namespaces. Thus e.g. any locale-using code on mingw will yield an error (include this file + string to see the result) 2. MSVCRT's _snprintf does not comply with C99 standard. Standard one is snprintf.

cd0129f5a6 Make some methods const. The only interesting change here is that
it changes raw_fd_ostream::preferred_buffer_size to return zero on
a scary stat failure instead of setting the stream to an error state.
This method really should not mutate the stream.
