82d96cccbc Grow BumpPtrAllocator's slab size dynamically if we allocated many slabs. This 
reduces the amount of malloc calls and may reduce memory overhead.

32cda119ef Add a new isSignWrappedSet() method to ConstantRange. 
Fix zeroExtend and signExtend to support empty sets, and to return the smallest
possible result set which contains the extension of each element in their
inputs. For example zext i8 [100, 10) to i16 is now [0, 256), not i16 [100, 10)
which contains 63446 members.

unexpected behavior in case they ever don't.

d4c454317a Make tool_output_file's raw_ostream instance a member variable instead

formatted_tool_output_file.

12881e79b6 Remove a hack that tries to understand incorrect triples from the 
Triple class constructor.  Only valid triples should now be used
inside LLVM - front-ends are now responsable for rejecting or
correcting invalid target triples.  The Triple::normalize method
can be used to straighten out funky triples provided by users.
Give this a whirl through the buildbots to see if I caught all
places where triples enter LLVM.

- On my core2 this code is faster except when the checked string was very short
  (smaller than the list of delimiters).

93d81b697c Fix the rest of rdar://8318441 which happens when a raw_fd_ostream 
(e.g. errs()) fails in close() due to (e.g.) a broken pipe.  As
previously written, the had_error() flag would get set and then
the raw_ostream dtor would report a fatal error.  There is nothing
the client can do about this and we have no way to report the error,
so just eat it.

335db22392 Add a 'normalize' method to the Triple class, which takes a mucked up 
target triple and straightens it out.  This does less than gcc's script
config.sub, for example it turns i386-mingw32 into i386--mingw32 not
i386-pc-mingw32, but it does a decent job of turning funky triples into
something that the rest of the Triple class can understand.  The plan
is to use this to canonicalize triple's when they are first provided
by users, and have the rest of LLVM only deal with canonical triples.
Once this is done the special case workarounds in the Triple constructor
can be removed, making the class more regular and easier to use.  The
comments and unittests for the Triple class are already adjusted in this
patch appropriately for this brave new world of increased uniformity.

d9082dfd9a CrashRecoveryContext: Add a simple POSIX implementation. 
- This works, but won't handle crashes on stack overflow, or signals delivered
   to a thread other than the one that crashed. The latter is particular annoying
   on Darwin, because SIGABRT tends to go to the main thread.

2a8bf425bd Rather than giving SmallPtrSetImpl a member field SmallArray which is magically 
replaced by a bigger array in SmallPtrSet (by overridding it), instead just use a
pointer to the start of the storage, and have SmallPtrSet pass in the value to use.
This has the disadvantage that SmallPtrSet becomes bigger by one pointer.  It has
the advantage that it no longer uses tricky C++ rules, and is clearly correct while
I'm not sure the previous version was.  This was inspired by g++-4.6 pointing out
that SmallPtrSetImpl was writing off the end of SmallArray, which it was.  Since
SmallArray is replaced with a bigger array in SmallPtrSet, the write was still to
valid memory.  But it was writing off the end of the declared array type - sounds
kind of dubious to me, like it sounded dubious to g++-4.6.  Maybe g++-4.6 is wrong
and this construct is perfectly valid and correctly compiled by all compilers, but
I think it is better to avoid the whole can of worms by avoiding this construct.

ea03e10fac Implement rdar://7415680 - Twine integer support lacks greatness 
Microoptimize Twine's with unsigned and int to not pin their value to
the stack.  This saves stack space in common cases and allows mem2reg
in the caller.  A simple example is:

void foo(const Twine &);
void bar(int x) {
  foo("xyz: " + Twine(x));
}

Before:

__Z3bari:
	subq	$40, %rsp
	movl	%edi, 36(%rsp)
	leaq	L_.str3(%rip), %rax
	leaq	36(%rsp), %rcx
	leaq	8(%rsp), %rdi
	movq	%rax, 8(%rsp)
	movq	%rcx, 16(%rsp)
	movb	$3, 24(%rsp)
	movb	$7, 25(%rsp)
	callq	__Z3fooRKN4llvm5TwineE
	addq	$40, %rsp
	ret

After:

__Z3bari:
	subq	$24, %rsp
	leaq	L_.str3(%rip), %rax
	movq	%rax, (%rsp)
	movslq	%edi, %rax
	movq	%rax, 8(%rsp)
	movb	$3, 16(%rsp)
	movb	$7, 17(%rsp)
	leaq	(%rsp), %rdi
	callq	__Z3fooRKN4llvm5TwineE
	addq	$24, %rsp
	ret

It saves 16 bytes of stack and one instruction in this case.

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.

valnos is not reliable for this purpose, as seen in r99400

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.

using a full APInt.

003a09c68d Substantially optimize APFloat::toString() by doing a single large divide to 
cut the significand down to the desired precision *before* entering the
core divmod loop.  Makes the overall algorithm logarithmic in the exponent.

There's still a lot of room for improvement here, but this gets the
performance back down to acceptable-for-diagnostics levels, even for
long doubles.

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.

Also, Stringrefify some more MemoryBuffer functions, and add two performance FIXMEs.

70197a3a04 add a new 'SetCurrentDebugType' API (requested by Andrew Haley for JIT

I'm at it, doxygenate Debug.h and clean it up.

0b22873adc r83391 was completely broken since Twines keep references to their inputs, and 
some of the inputs were temporaries.  Here's a real fix for the miscompilation.
Thanks to sabre for pointing out the problem.

and makes the API more annoying.  Add a Regex::getNumMatches() method.
