3523993451 reuse negates where possible instead of always creating them from scratch. 
This allows us to optimize test12 into:

define i32 @test12(i32 %X) {
  %factor = mul i32 %X, -3                        ; <i32> [#uses=1]
  %Z = add i32 %factor, 6                         ; <i32> [#uses=1]
  ret i32 %Z
}

instead of:

define i32 @test12(i32 %X) {
  %Y = sub i32 6, %X                              ; <i32> [#uses=1]
  %C = sub i32 %Y, %X                             ; <i32> [#uses=1]
  %Z = sub i32 %C, %X                             ; <i32> [#uses=1]
  ret i32 %Z
}

b76359e36e Optimize MDNode to coallocate the operand list immediately 
after the MDNode in memory.  This eliminates the operands
pointer and saves a new[] per node.

Note that the code in DIDerivedType::replaceAllUsesWith is wrong
and quite scary.  A MDNode should not be RAUW'd with something
else: this changes all uses of the mdnode, which may not be debug
info related!  Debug info should use something non-mdnode for
declarations.

54a1f9f9c1 do not bother reuniquing mdnodes whose operands drop to null. Doing 
so can be a huge performance issue when tearing down modules and mdnodes
are not guaranteed to be unique anyway.  This speeds up:
$ time ~/llvm/Release/bin/clang gcc.c -w -S -g

from 72 to 35s, where gcc.c is from:

e80250ec84 switch to TrackingVH instead of WeakVH, since these can never 
be RAUW'd and go to null.  This also gets us some sorely lacking
type safety.

a43a3f2379 When doing v1->RAUW(v2), don't do anything to metadata. We don't know 
why one was replaced with the other.  Even in the specific case of 
debug information, it doesn't make sense to transfer the location over,
this will just result in jumbled loc info.

cafe9bba32 add a layer of accessors around the Value::SubClassData member, and use 
a convention (shadowing the setter with private forwarding function) to
prevent subclasses from accidentally using it.

This exposed some bogosity in ConstantExprs, which was propaging the
opcode of the constant expr into the NUW/NSW/Exact field in the
getWithOperands/getWithOperandReplaced methods.

3990b121cf This is a major cleanup of the instruction metadata interfaces that 
I asked Devang to do back on Sep 27.  Instead of going through the
MetadataContext class with methods like getMD() and getMDs(), just
ask the instruction directly for its metadata with getMetadata()
and getAllMetadata().

This includes a variety of other fixes and improvements: previously
all Value*'s were bloated because the HasMetadata bit was thrown into
value, adding a 9th bit to a byte.  Now this is properly sunk down to
the Instruction class (the only place where it makes sense) and it
will be folded away somewhere soon.

This also fixes some confusion in getMDs and its clients about 
whether the returned list is indexed by the MDID or densely packed.
This is now returned sorted and densely packed and the comments make
this clear.

This introduces a number of fixme's which I'll follow up on.

079b6f5ee5 Add an "ATTRIBUTE_UNUSED" macro (and use it). It's for variables which are 
mainly used in debugging and/or assert situations. It should make the compiler
and the static analyzer stop nagging us about them.

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.
negligible, even on long doubles.

be much more efficient.

04b091a782 handle equality memcmp of 8 bytes on x86-64 with two unaligned loads and a 
compare.  On other targets we end up with a call to memcmp because we don't
want 16 individual byte loads.  We should be able to use movups as well, but
we're failing to select the generated icmp.

8047d9a6be move an optimization for memcmp out of simplifylibcalls and into 
SDISel.  This optimization was causing simplifylibcalls to 
introduce type-unsafe nastiness.  This is the first step, I'll be 
expanding the memcmp optimizations shortly, covering things that
we really really wouldn't want simplifylibcalls to do.
