Dan Gohman 390914cbe8 Make GlobalValue alignment consistent with load, store, and alloca 
alignment, fixing silent truncation of alignment values.

Jakob Stoklund Olesen f2234fbe70 Create a fixed stack object for varargs that is as large as any register. 
The size of this object isn't used for anything - technically it is of variable
size.

This avoids a false positive from the assert in
X86InstrInfo::loadRegFromStackSlot, and fixes PR7735.

Kevin Enderby e5930f142a Added first bit of support for the dwarf .file directive. This patch collects 
the info from the .file directive and makes file and directory tables that
will eventually be put out as part of the dwarf info in the output file.

Dan Gohman a7e5a24093 Define a maximum supported alignment value for load, store, and 
alloca instructions (constrained by their internal encoding),
and add error checking for it. Fix an instcombine bug which
generated huge alignment values (null is infinitely aligned).
This fixes undefined behavior noticed by John Regehr.

Daniel Dunbar 19a3b37441 Support: Add CrashRecoveryContext helper object. 
- Designed as a simple wrapper to allow clients to attempt to catch crashes
   (memory errors, assertion violations, etc.) and do some kind of recovery.

 - Currently doesn't actually attempt to catch crashes.

Dan Gohman 7a066723d0 Make SCEVCallbackVH::allUsesReplacedWith update the old SCEVUnknown 
object, as it may still be referenced by SCEVs not cleaned up by the
use list traversal.

Also, in ScalarEvolution::forgetValue, only check for a SCEVUnknown
object for the original value, not for any value in the use list,
because other SCEVUnknown values aren't necessary obsolete at that
point.

Nate Begeman 269a6da023 ~40% faster vector shl <4 x i32> on SSE 4.1 Larger improvements for smaller types coming in future patches. 
For:

define <2 x i64> @shl(<4 x i32> %r, <4 x i32> %a) nounwind readnone ssp {
entry:
  %shl = shl <4 x i32> %r, %a                     ; <<4 x i32>> [#uses=1]
  %tmp2 = bitcast <4 x i32> %shl to <2 x i64>     ; <<2 x i64>> [#uses=1]
  ret <2 x i64> %tmp2
}

We get:

_shl:                                   ## @shl
	pslld	$23, %xmm1
	paddd	LCPI0_0, %xmm1
	cvttps2dq	%xmm1, %xmm1
	pmulld	%xmm1, %xmm0
	ret

Instead of:

_shl:                                   ## @shl
	pshufd	$3, %xmm0, %xmm2
