6a9cd41549 Various improvements to MemoryBuffer::getFile: 
- Use a RAII object to close the FD.
- Use sys::StrError instead of thread-unsafe strerror calls.
- Recover gracefully if read returns zero. This works around an issue on
  DragonFlyBSD where /dev/null has an st_size of 136 but we can't read 136 bytes
  from it.

991de14dd6 Introduce SpecificBumpPtrAllocator, a wrapper for BumpPtrAllocator which allows 
only a single type of object to be allocated. Use it to make VNInfo destruction
typesafe.

2a22004f68 Introduce another Reset() method in BumpPtrAllocator that calls a destructor 
on all objects it has allocated, if they are all of the same size and alignment.
Use this to destruct all VNInfos allocated in LiveIntervalAnalysis (PR6653).

valnos is not reliable for this purpose, as seen in r99400
(which still leaked, and sometimes caused double frees).

fc86c3cfd6 remove support for per-time peak memory tracking, this 
isn't used by anyone and is better exposed as a non-per-timer 
thing.  Also, stop including System/Mutex.h in Timer.h

0ea86bc411 various timer fixes: move operator= out of line, 
eliminate the per-timer lock (timers should be 
externally locked if needed), the info-output-stream
can never be dbgs(), so drop the check.  Make some
stuff private.

c93b4cff89 Add the ability to "intern" FoldingSetNodeID data into a 
BumpPtrAllocator-allocated region to allow it to be stored in a more
compact form and to avoid the need for a non-trivial destructor call.

Use this new mechanism in ScalarEvolution instead of
FastFoldingSetNode to avoid leaking memory in the case where a
FoldingSetNodeID uses heap storage, and to reduce overall memory
usage.

1e7ad3993d Add an override to StringRef::getAsInteger which parses into an APInt. 
It gets its own implementation totally divorced from the (presumably
performance-sensitive) routines which parse into a uint64_t.

Add APInt::operator|=(uint64_t), which is situationally much better than
using a full APInt.

instead of sometimes making QNaNs and sometimes SNaNs depending on the
type.

a70f28ce7d Adding the MicroBlaze backend. 
The MicroBlaze is a highly configurable 32-bit soft-microprocessor for
use on Xilinx FPGAs. For more information see:
http://www.xilinx.com/tools/microblaze.htm
http://en.wikipedia.org/wiki/MicroBlaze

The current LLVM MicroBlaze backend generates assembly which can be
compiled using the an appropriate binutils assembler.

7e7ae5ad69 Refer to -help instead of --help since this is what tools themselves say.

every mention of --help, only those which seemed clearly safe.
