Anton Korobeynikov 29a44df5f8 ARM does not support offset folding (yet). Disable it for now.
This fixes PR5031. Unfortunately, there is no small testcase :(

Evan Cheng 9827ad39a7 Fix PR4926. When target hook EmitInstrWithCustomInserter() insert new basic blocks and update CFG, it should also inform sdisel of the changes so the phi source operands will come from the right basic blocks.

Evan Cheng 270d0f986f Enhance EmitInstrWithCustomInserter() so target can specify CFG changes that sdisel will use to properly complete phi nodes.
Not functionality change yet.

Jim Grosbach 20eac92d88 Clean up LSDA name generation and use for SJLJ exception handling. This
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
and making it a GV available for reference would be even better, but is
beyond the scope of what I'm looking to solve at this point.

Objective C++ code could generate function names that broke the previous
scheme. This fixes that.

Bob Wilson e0636a7aed Remove unneeded ARM-specific DAG nodes for VLD* and VST* Neon operations.
The instructions can be selected directly from the intrinsics.  We will need
to add some ARM-specific nodes for VLD/VST of 3 and 4 128-bit vectors, but
those are not yet implemented.

Bob Wilson 32cd8550ce Add support for Neon VEXT (vector extract) shuffles.
This is derived from a patch by Anton Korzh.  I modified it to recognize
the VEXT shuffles during legalization and lower them to a target-specific
DAG node.

Evan Cheng 52d4e64711 Change allowsUnalignedMemoryAccesses to take type argument since some targets
support unaligned mem access only for certain types. (Should it be size
instead?)

ARM v7 supports unaligned access for i16 and i32, some v6 variants support it
as well.

Anton Korobeynikov a6b3ce203a Allow targets to specify their choice of calling conventions per
libcall. Take advantage of this in the ARM backend to rectify broken
choice of CC when hard float is in effect. PIC16 may want to see if
it could be of use in MakePIC16Libcall, which works unchanged.

Patch by Sandeep!

Bob Wilson 6f34e278c7 Now that all the legal Neon shuffles (or at least the ones that have been
implemented so far) are recognized during legalization, it is easy to fall
back to the default expansion for other shuffles.

Bob Wilson eb54d51759 Create a new ARM-specific DAG node, VDUP, to represent a splat from a

Bob Wilson cce31f6831 During legalization, change Neon vdup_lane operations from shuffles to
target-specific VDUPLANE nodes.  This allows the subreg handling for the
quad-register version to be done easily with Pats in the .td file, instead
of with custom code in ARMISelDAGToDAG.cpp.
