d497ef1505 [Hexagon] Fix debug information for local objects
- Isolate the check for the existence of a stack frame into hasFP.
- Implement getFrameIndexReference for DWARF address computation.
- Use getFrameIndexReference for offset computation in eliminateFrameIndex.
- Preserve debug information for dynamically allocated stack objects.
- Prefer FP to access local objects at -O0.
- Add experimental code to skip allocframe when not strictly necessary
  (disabled by default).

6e76a23a66 Put back SelectionDAG::getTargetIndex.
While technically this is untested dead code, it has out-of-tree users.
This reverts a part of r250434.

65040b23fb [Orc] Add support for emitting indirect stubs directly into the JIT target's
memory, rather than representing the stubs in IR. Update the CompileOnDemand
layer to use this functionality.

Directly emitting stubs is much cheaper than building them in IR and codegen'ing
them (see below). It also plays well with remote JITing - stubs can be emitted
directly in the target process, rather than having to send them over the wire.

The downsides are:

(1) Care must be taken when resolving symbols, as stub symbols are held in a
    separate symbol table. This is only a problem for layer writers and other
    people using this API directly. The CompileOnDemand layer hides this detail.

(2) Aliases of function stubs can't be symbolic any more (since there's no
    symbol definition in IR), but must be converted into a constant pointer
    expression. This means that modules containing aliases of stubs cannot be
    cached. In practice this is unlikely to be a problem: There's no benefit to
    caching such a module anyway.

On balance I think the extra performance is more than worth the trade-offs: In a
simple stress test with 10000 dummy functions requiring stubs and a single
executed "hello world" main function, directly emitting stubs reduced user time
for JITing / executing by over 90% (1.5s for IR stubs vs 0.1s for direct
emission).

d6e77b7d15 llvm-lto support for generating combined function indexes
Summary:
This patch adds support to llvm-lto that mirrors the support added by
r249270 to the gold plugin. This enables better testing of combined
index generation for ThinLTO.

Added a new test, and this support will be used in the test in D13515.

52578b0850 Fix mapping of @llvm.arm.ssat/usat intrinsics to ssat/usat instructions
The mapping of these two intrinsics in ARMInstrInfo.td had a small
omission which lead to their operands not being validated/transformed
before being lowered into usat and ssat instructions. This can cause
incorrect instructions to be emitted.

I've also added tests for the remaining two saturating arithmatic
intrinsics @llvm.arm.qadd and @llvm.arm.qsub as they are missing
codegen tests.

f9cd1bee2f [GlobalsAA] Fix a really horrible iterator invalidation bug
We were keeping a reference to an object in a DenseMap then mutating it. At the end of the function we were attempting to clone that reference into other keys in the DenseMap, but DenseMap may well decide to resize its hashtable which would invalidate the reference!

It took an extremely complex testcase to catch this - many thanks to Zhendong Su for catching it in PR25225.

This fixes PR25225.

da40167c02 Removed parameter "Consecutive" from isLegalMaskedLoad() / isLegalMaskedStore().
Originally I planned to use the same interface for masked gather/scatter and set isConsecutive to "false" in this case.

Now I'm implementing masked gather/scatter and see that the interface is inconvenient. I want to add interfaces isLegalMaskedGather() / isLegalMaskedScatter() instead of using the "Consecutive" parameter in the existing interfaces.

09717fa07b Minor Instr PGO code restructuring
1. Key constant values (version, magic) and data structures related to raw and 
   indexed profile format are moved into one centralized file: InstrProf.h.
2. Utility function such as MD5Hash computation is also moved to the common 
   header to allow sharing with other components in the future.
3. A header data structure is introduced for Indexed format so that the reader
   and writer can always be in sync.
4. Added some comments to document different places where multiple definition
   of the data structure must be kept in sync (reader/writer, runtime, lowering 
   etc).  No functional change is intended.

2 - Converts INSERTQI/EXTRQI calls to shufflevector if the bit index/length are both byte aligned (we can already lower shuffles to INSERTQI/EXTRQI if its useful)
3 - Constant folding support
4 - Add zeroinitializer handling
