f9e4a986c0 Add a m_Undef pattern for convenience. This is so that code that uses 
pattern matching can also pattern match undef, creating a more uniform
style.

4de2c76542 Fix m_Not and m_Neg to not match random ConstantInt's. Before 
these would try hard to match constants by inverting the bits
and recursively matching.  There are two problems with this:
1) some patterns would match when we didn't want them to (theoretical)
2) this is insanely expensive to do, and most often pointless.

This was apparently useful in just 2 instcombine cases, which I
added code to handle explicitly.  This change speeds up 'opt'
time on 176.gcc by 1% and produces bitwise identical code.

998ef4a92d switch the second scalarrepl pass to use SSAUpdater. We run two scalarrepl passes: one 
early in the cleanup code and one late interlaced with the inliner.  The second one is
important because inlining and other scalar optzns can unpin allocas, allowing them to 
be split up and promoted.  While important for performance, this is also relatively
rare, and we would previously force a (non-lazy) computation of DomFrontiers, which 
happened even if nothing became unpinned.

With this patch, the first pass of scalarrepl still promotes the vast bulk of allocas
in programs, but hte second pass has changed to use SSAUpdater, which is more "sparse"
and lazy.  This speeds up opt -O3 time on kimwitu++ (a c++ app) by about 1%.  The
numbers are interesting: the first pass promotes ~17500 allocas.  The second pass
promotes about 1600.  For non-C++ codes, the compile time win should be greater, 
because the second pass of scalarrepl does less.

c5f608b49c Rather than doing early instcombine, try doing early CSE instead. This should still handle 
most important simplifications, as well as resolving phase ordering issues where instcombine
would inhibit important CSE'ing opportunities, for instance on BitBench/drop3.

bfb7dd9e9e Revert svn 122743, removing the instcombine pass that was replaced by earlycse. 
My i386 llvm-gcc nightly tester found a regression for
SingleSource/Benchmarks/McGill/chomp that a bisect blamed on 122743.
That seems strange but apparently the combination of earlycse and instcombine
did something bad.  Chris says he intended to remove the instcombine pass, so
let's go ahead and try that.  We'll see if there are any performance losses.

be478819cb Fix PR8906: -fno-builtin should disable loop-idiom recognition. 
It forms memset and memcpy's, and will someday form popcount and
other stuff.  All of this is bad when compiling the implementation
of memset, memcpy, popcount, etc.

db5f5e64fe Turn on earlycse by default. This seems to be a small performance 
improvement in the generated code, and speeds up 'opt -std-compile-opts'
compile time on 176.gcc from 24.84s to 23.2s (about 7%).

This also resolves a specific code quality issue in rdar://7352081 which
was generating poor code for:

int t(int a, int b) {
  if (a & b & 1)
    return a & b;
  return 3;
}

0fd8ee4995 turn on memset idiom recognition by default. Though there are still lots of 
limitations, this kicks in dozens of times in the 4 specfp2000 benchmarks, 
and hundreds of times in the int part.  It also kicks in hundreds of times 
in multisource.

This kicks in right before loop deletion, which has the pleasant effect of
deleting loops that *just* do a memset.

e27db74a60 improve switch formation to handle small range 
comparisons formed by comparisons.  For example,
this:

void foo(unsigned x) {
  if (x == 0 || x == 1 || x == 3 || x == 4 || x == 6) 
    bar();
}

compiles into:

_foo:                                   ## @foo
## BB#0:                                ## %entry
	cmpl	$6, %edi
	ja	LBB0_2
## BB#1:                                ## %entry
	movl	%edi, %eax
	movl	$91, %ecx
	btq	%rax, %rcx
	jb	LBB0_3

instead of:

_foo:                                   ## @foo
## BB#0:                                ## %entry
	cmpl	$2, %edi
	jb	LBB0_4
## BB#1:                                ## %switch.early.test
	cmpl	$6, %edi
	ja	LBB0_3
## BB#2:                                ## %switch.early.test
	movl	%edi, %eax
	movl	$88, %ecx
	btq	%rax, %rcx
	jb	LBB0_4

This catches a bunch of cases in GCC, which look like this:

 %804 = load i32* @which_alternative, align 4, !tbaa !0
 %805 = icmp ult i32 %804, 2
 %806 = icmp eq i32 %804, 3
 %or.cond121 = or i1 %805, %806
 %807 = icmp eq i32 %804, 4
 %or.cond124 = or i1 %or.cond121, %807
 br i1 %or.cond124, label %.thread, label %808

turning this into a range comparison.

2f5f90ad3e Implement PR8644: forwarding a memcpy value to a byval, 
allowing the memcpy to be eliminated.

Unfortunately, the requirements on byval's without explicit 
alignment are really weak and impossible to predict in the 
mid-level optimizer, so this doesn't kick in much with current
frontends.  The fix is to change clang to set alignment on all
byval arguments.

85a0a06b18 patch from Frits van Bommel: 
The attached patch fixes IRBuilder and the NoFolder class so that when
NoFolder is used the instructions it generates are treated just like
the ones IRBuilder creates directly (insert into block, assign them a
name and debug info, as applicable).
It does this by
1) having NoFolder return Instruction*s instead of Value*s,
2) having IRBuilder call Insert(Value, Name) on values obtained from
the folder like it does on instructions it creates directly, and
3) adding an Insert(Constant*, const Twine& = "") overload which just
returns the constant so that the other folders shouldn't have any
extra overhead as long as inlining is enabled.

While I was there, I also added some missing (CreateFNeg and various
Create*Cast) methods to NoFolder.
