Sanjoy Das ba0daee6b2 [StackMaps] Increase the size of the "location size" field 
Summary:
In some cases LLVM (especially the SLP vectorizer) will create vectors
that are 256 bytes (or larger).  Given that this is intentional[0] is
likely to get more common, this patch updates the StackMap binary
format to deal with the spill locations for said vectors.

This change also bumps the stack map version from 2 to 3.

Sanjoy Das 40c32dd9a0 Use a pointer type for target frame indices during statepoint lowering 
Summary:
The type of the target frame index is intptr, not the type of the value we're
going to store into it.  Without this change we crash in the attached test case
when trying to type-legalize a TargetFrameIndex.

Patchpoint lowering types the target frame index as intptr as well.

Sanjoy Das 0272be206a Don't force SP-relative addressing for statepoints 
Summary:
...  when the offset is not statically known.

Prioritize addresses relative to the stack pointer in the stackmap, but
fallback gracefully to other modes of addressing if the offset to the
stack pointer is not a known constant.

Patch by Oscar Blumberg!

Sanjoy Das 731c67fed2 Lower varargs correctly in deopt bundle lowering 
Earlier we were ignoring varargs in LowerCallSiteWithDeoptBundle because
populateCallLoweringInfo does not set CallLoweringInfo::IsVarArg.

Sanjoy Das eb5037cadc Allow lowering call sites with both funclets and deopt state 
Lowering funclets is a no-op, so we can just go ahead and lower the
deopt state.

Sanjoy Das dd1d72ce92 Appease the windows buildbots 
The guess is that the stdout/stderr ordering may differ between windows

Sanjoy Das 38bfc22161 Add "first class" lowering for deopt operand bundles 
Summary:
After this change, deopt operand bundles can be lowered directly by
SelectionDAG into STATEPOINT instructions (which are then lowered to a
call or sequence of nop, with an associated __llvm_stackmaps entry0.
This obviates the need to round-trip deoptimization state through
gc.statepoint via RewriteStatepointsForGC.
