Add a new capability to RegisterContextLLDB: To recognize when the
Full UnwindPlan is trying to do an impossible unwind; in that case
invalidate the Full UnwindPlan and replace it with the architecture
default unwind plan.
This is a scenario that happens occasionally with arm unwinds in
particular; the instruction analysis based full unwindplan can
mis-parse the functions and the stack walk stops prematurely. Now
we can do a simpleminded frame-chain walk to find the caller frame
and continue the unwind. It's not ideal but given the complicated
nature of analyzing the arm functions, and the lack of eh_frame
information on iOS, it is a distinct improvement and fixes some
long-standing problems with the unwinder on that platform.
This is fixing <rdar://problem/
12091421>. I may re-use this
invalidate feature in the future if I can identify other cases where
the full unwindplan's unwind information is clearly incorrect.

Begin incorporating target information into BBVectorize.
This is the first of several steps to incorporate information from the new
TargetTransformInfo infrastructure into BBVectorize. Two things are done here:
1. Target information is used to determine if it is profitable to fuse two
instructions. This means that the cost of the vector operation must not
be more expensive than the cost of the two original operations. Pairs that
are not profitable are no longer considered (because current cost information
is incomplete, for intrinsics for example, equal-cost pairs are still
considered).
2. The 'cost savings' computed for the profitability check are also used to
rank the DAGs that represent the potential vectorization plans. Specifically,
for nodes of non-trivial depth, the cost savings is used as the node
weight.
The next step will be to incorporate the shuffle costs into the DAG weighting;
this will give the edges of the DAG weights as well. Once that is done, when
target information is available, we should be able to dispense with the
depth heuristic.

add TableGen support to create relationship maps between instructions
Relationship maps are represented as InstrMapping records which are parsed by
TableGen and the information is used to construct mapping tables to represent
appropriate relations between instructions. These tables are emitted into
XXXGenInstrInfo.inc file along with the functions to query them.

This patch fixes the MC object emission of 'nop' for external function calls
and also fixes the R_PPC64_TOC16 and R_PPC64_TOC16_DS relocation offset.
The 'nop' is needed so a restore TOC instruction (ld r2,40(r1)) can be placed
by the linker to correct restore the TOC of previous function.
Current code has two issues: it defines in PPCInstr64Bit.td file a LDinto_toc
and LDtoc_restore as a DSForm_1 with DS_RA=0 where it should be
DS=2 (the 8 bytes displacement of the TOC saving). It also wrongly emits a
MC intruction using an uint32_t value while the PPC::BL8_NOP_ELF
and PPC::BLA8_NOP_ELF are both uint64_t (because of the following 'nop').
This patch corrects the remaining ExecutionEngine using MCJIT:

This patch addresses a PPC64 ELF issue with passing parameters consisting of
structs having size 3, 5, 6, or 7. Such a struct must be passed and received
as right-justified within its register or memory slot. The problem is only
present for structs that are passed in registers.
Previously, as part of a patch handling all structs of size less than 8, I
added logic to rotate the incoming register so that the struct was left-
justified prior to storing the whole register. This was incorrect because
the address of the parameter had already been adjusted earlier to point to
the right-adjusted value in the storage slot. Essentially I had accidentally
accounted for the right-adjustment twice.
In this patch, I removed the incorrect logic and reorganized the code to make
the flow clearer.
The removal of the rotates changes the expected code generation, so test case
structsinregs.ll has been modified to reflect this. I also added a new test
case, jaggedstructs.ll, to demonstrate that structs of these sizes can now
be properly received and passed.
I've built and tested the code on powerpc64-unknown-linux-gnu with no new
regressions. I also ran the GCC compatibility test suite and verified that
earlier problems with these structs are now resolved, with no new regressions.

Initial TOC support for PowerPC64 object creation
This patch adds initial PPC64 TOC MC object creation using the small mcmodel
(a single 64K TOC) adding the some TOC relocations (R_PPC64_TOC,
R_PPC64_TOC16, and R_PPC64_TOC16DS).
The addition of 'undefinedExplicitRelSym' hook on 'MCELFObjectTargetWriter'
is meant to avoid the creation of an unreferenced ".TOC." symbol (used in
the .odp creation) as well to set the R_PPC64_TOC relocation target as the
temporary ".TOC." symbol. On PPC64 ABI, the R_PPC64_TOC relocation should
not point to any symbol.
