When using CrashRecoveryContext::RunSafelyOnThread, we would set a CrashRecoveryContextImpl* to a thread-local variable

The result was that if CrashRecoveryContext::RunSafelyOnThread was called again in the "child" thread it would mess up

DebugInfo: PR14763/r183329 correct the location of indirect parameters
We had been papering over a problem with location info for non-trivial
types passed by value by emitting their type as references (this caused
the debugger to interpret the location information correctly, but broke
the type of the function). r183329 corrected the type information but
lead to the debugger interpreting the pointer parameter as the value -
the debug info describing the location needed an extra dereference.
Use a new flag in DIVariable to add the extra indirection (either by
promoting an existing DW_OP_reg (parameter passed in a register) to
DW_OP_breg + 0 or by adding DW_OP_deref to an existing DW_OP_breg + n

[MC/DWARF] Generate multiple .debug_line entries for adjacent .loc directives
The compiler occasionally generates multiple .loc directives in a row
(at the same instruction address). These need to be transformed into
multple actual .debug_line table entries, since they are used to signal
certain information to the debugger (e.g. if the opening brace of a
function body is on the same line as the declaration).
The MCAsmStreamer version of EmitDwarfLocDirective handles this
correctly by emitting a .loc directive every time it is called.
However, the MCObjectStream version simply defaults to recording
the information and emitting only a single table entry later,
e.g. when EmitInstruction is called.
This patch introduces a MCAsmStreamer::EmitDwarfLocDirective
version that emits a line table entry for a .loc directive
that may already be pending before recording the new directive.
(This is similar to how this is handled in GNU as.)
With this patch (and the code alignment factor patch) applied,
I'm now getting identical DWARF .debug sections for all test-suite
object files on PowerPC for the internal and the external assembler.

comment out isNormal locally and continually convert isNormal references =>

Converted an overly aggressive assert to a conditional check in AddCombineTo64bitMLAL.
Said assert assumes that ADDC will always have a glue node as its second
argument and is checked before we even know that we are actually performing the
relevant MLAL optimization. This is incorrect since on ARM we *CAN* codegen ADDC
with a use list based second argument. Thus to have both effects, I converted
the assert to a conditional check which if it fails we do not perform the
optimization.
In terms of tests I can not produce an ADDC from the IR level until I get in my
multiprecision optimization patch which is forthcoming. The tests for said patch
would cause this assert to fail implying that said tests will provide the
relevant tests.

Change the arm assembler to support this from the v7c spec:
"When assembling to the ARM instruction set, the .N qualifier produces
an assembler error and the .W qualifier has no effect."
In the pre-matcher handler in the asm parser the ".w" (wide) qualifier
when in ARM mode is now discarded. And an error message is now
produced when the ".n" (narrow) qualifier is used in ARM mode.
Test cases for these were added.

Mips ELF: Mark object file as ABI compliant
When producing objects that are abi compliant we are
marking neither the object file nor the assembly file
correctly and thus generate warnings.
We need to set the EF_CPIC flag in the ELF header when
generating direct object.
Note that the warning is only generated when compiling without PIC.
When compiling with clang the warning will be suppressed by supplying:
-Wa,-mno-shared -Wa,-call_nonpic
Also the following directive should also be added:
.option pic0
when compiling without PIC, This eliminates the need for supplying:
-mno-shared -call_nonpic
on the assembler command line.
