6b1207267f Generalize PostRAHazardRecognizer so it can be used in any pass for 
both forward and backward scheduling. Rename it to
ScoreboardHazardRecognizer (Scoreboard is one word). Remove integer
division from the scoreboard's critical path.

cba2e06d52 Stub out RegAllocGreedy. 
This new register allocator is initially identical to RegAllocBasic, but it will
receive all of the tricks that RegAllocBasic won't get.

RegAllocGreedy will eventually replace linear scan.

Minor optimization to the use of IntervalMap iterators. They are fairly
heavyweight, so prefer SI.valid() over SI != end().

4f4363a490 Layout each section independently. With the testcase in PR8711: 
before:
        4 assembler - Number of assembler layout and relaxation steps
    78563 assembler - Number of emitted assembler fragments
  8693904 assembler - Number of emitted object file bytes
   271223 assembler - Number of evaluated fixups
330771677 assembler - Number of fragment layouts
     5958 assembler - Number of relaxed instructions
  2508361 mcexpr    - Number of MCExpr evaluations

real	0m26.123s
user	0m25.694s
sys	0m0.388s

after:

      4 assembler - Number of assembler layout and relaxation steps
  78563 assembler - Number of emitted assembler fragments
8693904 assembler - Number of emitted object file bytes
 271223 assembler - Number of evaluated fixups
 231507 assembler - Number of fragment layouts
   5958 assembler - Number of relaxed instructions
2508361 mcexpr    - Number of MCExpr evaluations

real	0m2.500s
user	0m2.113s
sys	0m0.273s

And yes, the outputs are identical :-)

vpush instructions to save / restore VFP / NEON registers like this:
vpush {d8,d10,d11}
vpop {d8,d10,d11}

vpush and vpop do not allow gaps in the register list.

a6399ae089 Remove the code from Function::dropAllReferences which replaced 
uses of the function's blocks with undef. This code isn't needed,
because BasicBlock's destructor handles such uses. Also, undef isn't
correct, since blockaddresses may still be used for comparisons
with null.

85f2ecc697 Sorry for such a large commit. The summary is that only MachO cares about the 
actuall addresses in a .o file, so it is better to let the MachO writer compute
it.

This is good for two reasons. First, areas that shouldn't care about
addresses now don't have access to it. Second, the layout of each section
is independent. I should use this in a subsequent commit to speed it up.

Most of the patch is just removing the section address computation. The two
interesting parts are the change on how we handle padding in the end
of sections and how MachO can get the address of a-b when a and b are in
different sections.

Since now the expression evaluation normally doesn't know the section address,
it will think that a-b needs relocation and let the MachO writer know. Once
it has computed the section addresses, it calls back the expression evaluation
with the section addresses to resolve these expressions.

The remaining problem is the handling of padding. Currently it will create
a special alignment fragment at the end. Since that fragment doesn't update
the alignment of the section, it needs the real address to be computed.

Since now the layout will not compute a-b with a and b in different sections,
the only effect that the special alignment fragment has is update the
address size of the section. This can also be done by the MachO writer.

6c3ee0f3c9 Fix PR8735, a really terrible problem in the inliner's "alloca merging" 
optimization.

Consider:
static void foo() {
  A = alloca
  ...
}

static void bar() {
  B = alloca
  ...
  call foo();
}

void main() {
  bar()
}

The inliner proceeds bottom up, but lets pretend it decides not to inline foo
into bar.  When it gets to main, it inlines bar into main(), and says "hey, I
just inlined an alloca "B" into main, lets remember that.  Then it keeps going
and finds that it now contains a call to foo.  It decides to inline foo into
main, and says "hey, foo has an alloca A, and I have an alloca B from another
inlined call site, lets reuse it".  The problem with this of course, is that 
the lifetime of A and B are nested, not disjoint.

Unfortunately I can't create a reasonable testcase for this: the one in the
PR is both huge and extremely sensitive, because you minor tweaks end up
causing foo to get inlined into bar too early.  We already have tests for the
basic alloca merging optimization and this does not break them.

memcpy's like:
  memcpy(A, B)
  memcpy(A, C)

we cannot delete the first memcpy as dead if A and C might be aliases.
If so, we actually get:

  memcpy(A, B)
  memcpy(A, A)

which is not correct to transform into:

  memcpy(A, A)
