[RuntimeDyld] Fix ppc64 stub relocations on little-endian
When RuntimeDyldELF creates stub functions, it needs to install
relocations that will resolve to the final address of the target
routine. Since those are 16-bit relocs, they need to be applied to the
least-significant halfword of the instruction. On big-endian ppc64,
this means that addresses have to be adjusted by 2, which is what the
code currently does.
However, on a little-endian system, the address must *not* be adjusted;
the least-significant halfword is the first one. This patch updates the
RuntimeDyldELF code to take the target byte order into account.

[PowerPC] Fix small argument stack slot offset for LE
When small arguments (structures < 8 bytes or "float") are passed in a
stack slot in the ppc64 SVR4 ABI, they must reside in the least
significant part of that slot. On BE, this means that an offset needs
to be added to the stack address of the parameter, but on LE, the least
significant part of the slot has the same address as the slot itself.
This changes the PowerPC back-end ABI code to only add the small
argument stack slot offset for BE. It also adds test cases to verify
the correct behavior on both BE and LE.

The tools/lto API is not the best choice for implementing a gold plugin. Among
other issues:
* It is an stable ABI. Old errors stay and we have to be really careful

* It has to support two fairly different linkers: gold and ld64.
* We end up with a plugin that depends on a shared lib, something quiet
unusual in LLVM land.
* It hides LLVM. For some features in the gold plugin it would be really

Rename computeKnownBitsLoad to computeKnownBitsFromRangeMetadata because
range metadata is not only used by load.
Update the language reference to reflect this change.

Add two tests in AddOverFlow.ll to confirm annotating range metadata to

Emit DWARF3 call frame information when DWARF3+ debug info is requested
Currently, llvm always emits a DWARF CIE with a version of 1, even when emitting
DWARF 3 or 4, which both support CIE version 3. This patch makes it emit the
newer CIE version when we are emitting DWARF 3 or 4. This will not reduce
compatibility, as we already emit other DWARF3/4 features, and is worth doing as
the DWARF3 spec removed some ambiguities in the interpretation of call frame
information.
It also fixes a minor bug where the "return address" field of the CIE was
encoded as a ULEB128, which is only valid when the CIE version is 3. There are
no test changes for this, because (as far as I can tell) none of the platforms
that we test have a return address register with a DWARF register number >127.

Replace Execution Engine's mutex with std::recursive_mutex.
This change has a bit of a trickle down effect due to the fact that
there are a number of derived implementations of ExecutionEngine,
and that the mutex is not tightly encapsulated so is used by other
classes directly.

Revert a C API difference that I incorrectly introduced.
LLVMGetBitcodeModuleInContext should not take ownership on error. I will
