Jim Grosbach 3e941aee69 ARM thumb assembly parsing for arithmetic flag setting instructions.
Thumb one requires that many arithmetic instruction forms have an 'S'
suffix. For Thumb2, the whether the suffix is required or precluded depends
on whether the instruction is in an IT block. Use target parser predicates
to check for these sorts of context-sensitive constraints.

Bill Wendling 8ddfc09e7a Use the getFirstInsertionPt() method instead of getFirstNonPHI + an 'isa<>'
check for a LandingPadInst.

Bill Wendling ee1c2d2437 Add getFirstInsertionPt() method.
getFirstInsertionPt() returns an iterator to the first insertion point in a
basic block. This is after all PHIs and any other instruction which is required
to be at the top of the basic block (like LandingPadInst).

Greg Clayton 72da397a69 Fixed an issue where we could end up creating multiple
C++ methods for a function depending on how the DWARF was 
created. Now we parse the class type from the definition,
and all methods that use DW_AT_specification or DW_AT_abstract_origin
attributes to point to the definition, now won't create
duplicate entries. This is in response to how clang++ creates
much different DWARF than gcc.

Bruno Cardoso Lopes 2e99f1b3aa Instead of always leaving the work to the generic legalizer when
there is no support for native 256-bit shuffles, be more smart in some
cases, for example, when you can extract specific 128-bit parts and use
regular 128-bit shuffles for them. Example:

For this shuffle:
  shufflevector <4 x i64> %a, <4 x i64> %b, <4 x i32>
                <i32 1, i32 0, i32 7, i32 6>

This was expanded to:
  vextractf128  $1, %ymm1, %xmm2
  vpextrq $0, %xmm2, %rax
  vmovd %rax, %xmm1
  vpextrq $1, %xmm2, %rax
  vmovd %rax, %xmm2
  vpunpcklqdq %xmm1, %xmm2, %xmm1
  vpextrq $0, %xmm0, %rax
  vmovd %rax, %xmm2
  vpextrq $1, %xmm0, %rax
  vmovd %rax, %xmm0
  vpunpcklqdq %xmm2, %xmm0, %xmm0
  vinsertf128 $1, %xmm1, %ymm0, %ymm0
  ret

Now we get:
  vshufpd $1, %xmm0, %xmm0, %xmm0
  vextractf128  $1, %ymm1, %xmm1
  vshufpd $1, %xmm1, %xmm1, %xmm1
  vinsertf128 $1, %xmm1, %ymm0, %ymm0

Enrico Granata be93a35a8a Python commands:
It is now possible to use 'command alias --python' to define a command name that actually triggers execution of a Python function
 (e.g. command alias --python foo foo_impl makes a command named 'foo' that runs Python function 'foo_impl')
 The Python function foo_impl should have as signature: def foo_impl(debugger, args, stream, dict): where
  debugger is an object wrapping an LLDB SBDebugger
  args is the command line arguments, as an unparsed Python string
  stream is an SBStream that represents the standard output
  dict is an internal utility parameter and should be left untouched
 The function should return None on no error, or an error string to describe any problems

Akira Hatanaka 2263c10946 Fix handling of double precision loads and stores when Mips1 is targeted.
Mips1 does not support double precision loads or stores, therefore two single
precision loads or stores must be used in place of these instructions. This 
patch treats double precision loads and stores as if they are legal
instructions until MCInstLowering, instead of generating the single precision
instructions during instruction selection or Prolog/Epilog code insertion.

Without the changes made in this patch, llc produces code that has the same 
problem described in r137484 or bails out when
MipsInstrInfo::storeRegToStackSlot or loadRegFromStackSlot is called before
register allocation.
