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
scalar_to_vector.  Generate these VDUP nodes during legalization instead
of trying to recognize the pattern during selection.

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.

Chris Lattner fe27130454 split "JumpTableDirective" (an existing hack) into a PIC and nonPIC
version.  This allows TAI implementations to specify the directive to use
based on the mode being codegen'd for.

The real fix for this is to remove JumpTableDirective, but I don't feel
like diving into the jumptable snarl just now.

Evan Cheng 3606467709 Fix Thumb2 load / store addressing mode matching code. Do not use so_reg form to
match base only address, i.e. [r] since Thumb2 requires a offset register field.
For those, use [r + imm12] where the immediate is zero.
Note the generated assembly code does not look any different after the patch.
But the bug would have broken the JIT (if there is Thumb2 support) and it can
break later passes which expect the address mode to be well-formed.

Bob Wilson 12842f9865 Use vAny type to get rid of Neon intrinsics that differed only in whether
the overloaded vector types allowed floating-point or integer vector elements.
Most of these operations actually depend on the element type, so bitcasting
was not an option.

If you include the vpadd intrinsics that I updated earlier, this gets rid
of 20 intrinsics.

Jim Grosbach 693e36a3e8 SjLj based exception handling unwinding support. This patch is nasty, brutish

The front-end generates the register/unregister calls into the SjLj runtime,
call-site indices and landing pad dispatch. The back end fills in the LSDA
with the call-site information provided by the front end. Catch blocks are
not yet implemented.

Chris Lattner cb307a27bf Make the big switch: Change MCSectionMachO to represent a section *semantically*
instead of syntactically as a string.  This means that it keeps track of the 
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and 
"attribute(section)", so we should now start getting errors about invalid 
section attributes from the compiler instead of the assembler on darwin.

Still todo: 
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
   S_GB_ZEROFILL segment type?
