0f706ab789 Move the extern symbol declarations outside of 
DynamicLibrary::SearchForAddressOfSymbol and force them to have "C"
linkage. 

Interestingly, GCC treats the block-scoped "extern" declarations we
previously had as if they were extern "C" declarations (or, at least,
were in the global namespace), so that GCC bug papered over this LLVM
bug. Clang and EDG get the linkage correct; this new variant seems to
work for both GCC and Clang.

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.

6a38182471 stop pattern matching 16-bit zero's of a register to MOV16r0, 
instead use the appropriate subreggy thing.  This generates identical
code on some large apps (thanks to Evan's cross class coalescing
stuff he did back in july).  This means that MOV16r0 can go away
completely in the future soon.

c5818fb837 Partially revert r91626. Materializing extra functions to determine whether 
they're available_externally broke VMKit, which was relying on the fact that
functions would only be materialized when they were first called.  We'll have
to wait for http://llvm.org/PR5737 to really fix this.

I also added a test for one of the F->isDeclaration() calls which wasn't
covered by anything else in the test suite.

aadadb3973 Fix the Convert to scalar to not insert dead loads in the store case. The 
load is needed when we have a small store into a large alloca (at which 
point we get a load/insert/store sequence), but when you do a full-sized
store, this load ends up being dead.

This dead load is bad in really large nasty testcases where the load ends
up causing mem2reg to insert large chains of dependent phi nodes which only
ADCE can delete.  Instead of doing this, just don't insert the dead load.

This fixes rdar://6864035
