e73a31f667 Stop building RTTI information for *most* llvm libraries. Notable 
missing ones are libsupport, libsystem and libvmcore.  libvmcore is
currently blocked on bugpoint, which uses EH.  Once it stops using
EH, we can switch it off.

This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

these adds in the correct location.

839a0159c4 It turns out that this #include is needed because otherwise 
ValueMapper.cpp ends up calling an out of line 
__ZNK4llvm12PATypeHolder3getEv, which is a template and llvm-config
determines arbitrarily to use the one in libipo.  This sucks, but
keeping the #include is a reasonable workaround.

401f3258f6 Fix a crasher trying to fold each element in a comparison between two vectors 
if one of the vectors didn't have elements (such as undef). Fixes PR 6096.

have <2 x i1> type if constant folding was successful and i1 type if it wasn't.

a10756ee65 Re-implement the main strength-reduction portion of LoopStrengthReduction. 
This new version is much more aggressive about doing "full" reduction in
cases where it reduces register pressure, and also more aggressive about
rewriting induction variables to count down (or up) to zero when doing so
reduces register pressure.

It currently uses fairly simplistic algorithms for finding reuse
opportunities, but it introduces a new framework allows it to combine
multiple strategies at once to form hybrid solutions, instead of doing
all full-reduction or all base+index.

d8d0b6a42c When doing address-mode sinking, expand the base register first, rather 
than the scaled register. This makes it more likely that subsequent
AddrModeMatcher queries will match the new address the same way as the
old, instead of accidentally matching what had been the base register
as the new scaled register, and then failing to match the scaled register.
This fixes some problems with address-mode sinking multiple muls into a
block, which will be a lot more common with some upcoming
LoopStrengthReduction changes.

e45ab8a0a9 For aligned load/store instructions, it's only required to know whether a 
function can support dynamic stack realignment. That's a much easier question
to answer at instruction selection stage than whether the function actually
will have dynamic alignment prologue. This allows the removal of the
stack alignment heuristic pass, and improves code quality for cases where
the heuristic would result in dynamic alignment code being generated when
it was not strictly necessary.

74bfe21b50 Now that we have everything nicely factored (e.g. asmprinter is not 
doing global variable classification anymore) and hookized, sink almost
all target targets global variable emission code into AsmPrinter and out
of each target.

Some notes:

1. PIC16 does completely custom and crazy stuff, so it is not changed.
2. XCore has some custom handling for extra directives.  I'll look at it next.
3. This switches linux/ppc to use .globl instead of .global.  If .globl is
   actually wrong, let me know and I'll fix it.
4. This makes linux/ppc get a lot of random cases right which were obviously
   wrong before, it is probably now a bit healthier.
5. Blackfin will probably start getting .comm and other things that it didn't
   before.  If this is undesirable, it should explicitly opt out of these
   things by clearing the relevant fields of MCAsmInfo.

This leads to a nice diffstat:

619ea855e7 more cleanups. Emit the .local directive even on cygwin/mingw. 
I'm not sure that this is correct, but it causes no test failures,
and just emitting a .comm without protecting its linkage somehow
is surely not right.

48d64ba9d8 hoist handling of external globals and special globals up to common code. 
This makes a similar code dead in all the other targets, I'll clean it up
in a bit.

This also moves handling of lcomm up before acquisition of a section,
since lcomm never needs a section.

aac138e84d Cleanup handling of .zerofill on darwin: 
1. TargetLoweringObjectFileMachO should decide if something
   goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
   the right MCSection, the asmprinters should just emit to the
   right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
   MAI can have a bool "haszerofill" instead of having the textual
   directive to emit.

1ad0e8b576 Canonicalize -1 - x to ~x. 
Instcombine does this but apparently there are situations where this pattern will escape the optimizer and / or created by isel. Here is a case that's seen in JavaScriptCore:
  %t1 = sub i32 0, %a
  %t2 = add i32 %t1, -1
The dag combiner pattern: ((c1-A)+c2) -> (c1+c2)-A
will fold it to -1 - %a.

the other one.

having to pass various fields from it in.  Simplify.

3a4a832223 The Neon "vtst" instruction takes a suffix that is the element size alone -- 
adding an "i" to the suffix, indicating that the elements are integers, is
accepted but not part of the standard syntax.  This helps us pass a few more
of the Neon tests from gcc.
