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.

5e6a705985 Let BumpPtrAllocator lazily allocate the first slab. 
We have some code in llvm and clang where a BumpPtrAllocator is declared in a
class but never used in the common case. Stop wasting memory there.

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.

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).

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.

7e7ae5ad69 Refer to -help instead of --help since this is what tools themselves say. 
Also, have tools output -help-hidden rather than refer to --help-hidden,
for consistency, and likewise adjust documentation.  This doesn't change
every mention of --help, only those which seemed clearly safe.

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.

- This is a pretty slow / memory intensive implementation, and I will likely
   change it to an iterative model, but it works.

37628e0098 Move the handling of CommaSeparated options into ProvideOption. 
Makes '--comma-separated val1,val2' mean the same thing as
'--comma-separated=val1,val2' (that is, 'val1' and 'val2' are not lumped
together as 'val1,val2'). Also declutters the main loop a bit.
