61fcfc6d86 When performing the Horrible Hack(tm-Duncan) on the EH code to convert a 
clean-up to a catch-all after inlining, take into account that there could be
filter IDs as well. The presence of filters don't mean that the selector catches
anything. It's just metadata information.

470551e0ef Add a missing bitcast. This code used to only handle conversions between 
i64 and f64 types, but now it also handle Neon vector types, so the f64 result
of VMOVDRR may need to be converted to a Neon type.  Radar 8084742.

5e3c60fb63 Add instruction encoding for the Neon VMOV immediate instruction. This changes 
the machine instruction representation of the immediate value to be encoded
into an integer with similar fields as the actual VMOV instruction.  This makes
things easier for the disassembler, since it can just stuff the bits into the
immediate operand, but harder for the asm printer since it has to decode the
value to be printed.  Testcase for the encoding will follow later when MC has
more support for ARM.

fade2aeb9f Define ContextualFoldingSet, which stores a context parameter to pass down to 
the Profile method.  Currently this only works with the default FoldingSetTraits
implementation.

The point of this is to allow nodes to not store context values which are only
used during profiling.  A better solution would thread this value through the
folding algorithms, but then those would need to be (1) templated and
(2) non-opaque.

48e353b393 Avoid "variable 'bits' set but not used [-Wunused-but-set-variable]"

83a8bdd9b7 Avoid many "variable 'Sub' set but not used [-Wunused-but-set-variable]" warnings 
with gcc-4.6.  The warning is wrong, since Sub *is* used (perhaps gcc is confused
because the use of Sub is constant folded away?), but since it is trivial to avoid,
and massively reduces the amount of warning spew, just workaround the wrong warning.

78593d094f Add includes to get ptrdiff_t. This is needed by gcc-4.6 which has 
done some more header trimming, resulting in cstdef being included

a239e93a5c be slightly more subtle about skipping dbg_value instructions; otherwise, if a 
dbg_value immediately follows a sequence of ldr/str instructions that should
be combined into an ldm/stm and is the last instruction in the block, then
combine may end up being skipped.

9611ad3317 Mark physregs defined by inline asm as implicit. 
This is a bit of a hack to make inline asm look more like call instructions.

c49bf683d9 It's an error to translate this: 
%reg1025 = <sext> %reg1024
    ...
   %reg1026 = SUBREG_TO_REG 0, %reg1024, 4

into this:

   %reg1025 = <sext> %reg1024
    ...
   %reg1027 = EXTRACT_SUBREG %reg1025, 4
   %reg1026 = SUBREG_TO_REG 0, %reg1027, 4

The problem here is that SUBREG_TO_REG is there to assert that an implicit zext
occurs. It doesn't insert a zext instruction. If we allow the EXTRACT_SUBREG
here, it will give us the value after the <sext>, not the original value of
%reg1024 before <sext>.
