94366111d3 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.

1114f568bc 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.

1a913ed178 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.

edce58fbd9 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.

db03adb346 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.

d64ba3ee62 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>.

d847124211 Thumb2 IT blocks are fairly expensive. When there are multiple selects using
the same condition, it's important to make sure they are scheduled together
to avoid forming multiple IT blocks. I'm adding a pre-regalloc pass that forms
IT blocks early (by re-scheduling instructions and split basic blocks) to
attempt to fix this. This is not turned on by default since I am not sure this
is the right fix.

Another issue is llvm selects are modeled as two-address conditional moves.
This can be very bad when the copies before the conditional moves are not
coalesced away. Teach IT formation pass to move the copies above the IT block
(when legal) to avoid breaking the IT block.

09712b57ce Incremental improvement to the handling of the x86 "Jump if rCX Zero"
instruction.  Added the 64-bit version "jrcxz" so it is recognized and also
added the checks for incorrect uses of "jcxz" in 64-bit mode and "jrcxz" in
32-bit mode.  Still to do is to correctly handle the encoding of the
instruction adding the Address-size override prefix byte, 0x67, when the width
of the count register is not the same as the mode the machine is running in.
Which for example means the encoding of "jecxz" depends if you are assembling
as a 32-bit target or a 64-bit target.
