This commit was reverted in r217183, but is OK to go in again now that its dependency is commited (as of r217186).

The special case did not work when run under -reassociate and can easily
be expressed by a further generalization of an existing pattern.

The header contains an offset to the DWARF line table for the CU. The offset
must be section relative for COFF and absolute for others. The non-assembly
code path for the DWARF header generation already has the correct emission for
the headers. This corrects the assembly input path.
This was identified by BFD objecting to the LLVM generated DWARF information.

Patched by Sergey Dmitrouk.
This pass tries to make consecutive compares of values use same operands to
allow CSE pass to remove duplicated instructions. For this it analyzes
branches and adjusts comparisons with immediate values by converting:
GE -> GT
GT -> GE
LT -> LE
LE -> LT
and adjusting immediate values appropriately. It basically corrects two
immediate values towards each other to make them equal.

Deleted CodeGen\MachineCodeInfo.h which was used by runJITOnFunction() only.

This reverts commit 93c7e6161e1adbd2c7ac81fa081823183035cb64.
This commit got approved first, but was dependant on another one going in (The one pretty printing attribute values). I'll reapply when the other one is in.

Summary:
This fixes a long standing issue where we would emit many little .text
sections and only one .pdata and .xdata section. Now we generate one
.pdata / .xdata pair per .text section and associate them correctly.
Fixes PR19667.

This fixes an issue where MS inline assembly containing xgetbv wouldn't
be marked as clobbering EAX:EDX. Test for that forthcoming on the Clang
side.

This adds the printing of more load commands, so that the normal load commands
in a typical X86 Mach-O executable can all be printed.

Follow up to r217138, extending the logic to other NEON-immediate instructions.
As before, the instruction already performs the correct operation and we're
just using a different type for convenience, so we want a true nop-cast.

Fixes:
CMake Warning (dev) at lib/ExecutionEngine/Interpreter/CMakeLists.txt:16 (target_link_libraries):
Policy CMP0023 is not set: Plain and keyword target_link_libraries
signatures cannot be mixed. Run "cmake --help-policy CMP0023" for policy
details. Use the cmake_policy command to set the policy and suppress this
warning.
The keyword signature for target_link_libraries has already been used with
the target "LLVMInterpreter". All uses of target_link_libraries with a
target should be either all-keyword or all-plain.
The uses of the keyword signature are here:

We were materialising big-endian constants using DAG nodes with types different
from what was requested, followed by a bitcast. This is fine on little-endian
machines where bitcasting is a nop, but we need a slightly different
representation for big-endian. This adds a new set of NVCAST (natural-vector
cast) operations which are always nops.

vzext patterns and insert-element patterns that for SSE4 have dedicated
instructions.
With this we can enable the experimental mode in a regression test that
happens to cover some of the past set of issues. You can see that the
new logic does significantly better here on the floating point cases.
A follow-up to this change and the previous ones will hoist the logic
into helpers so it can be shared across element type sizes as in this
particular case it generalizes cleanly.

The DWARFContext will be used to pass global 'context' down, like
pointers to related debug info sections or command line options.
The first use will be for the debug_info dumper to be able to access
other debug info section to dump eg. Location Expression inline
in the debug_info dump.

This allows fine-grained control of the memory layout of hypothetical target

abilities of INSERTPS which are really powerful and come up in very
important contexts such as forming diagonal matrices, etc.
With this I ended up being able to remove the somewhat weird helper
I added for INSERTPS because we can collapse the entire state to a no-op
mask. Added a bunch of tests for inserting into a zero-ish vector.

attributes can be added that have 0 as a legitimate value.
