The next step is to actually use unique_ptr in TreePatternNode's
Children vector. That will be more intrusive, and may not work,
depending on exactly how these things are handled (I have a bad
suspicion things are shared more than they should be, making this more
DAG than tree - but if it's really a tree, unique_ptr should suffice)

This was emitting the following assembly to get the value of %addr1:
add r0, sp, #1020
add r0, r0, #8
However, "add r0, r0, #8" is not a valid Thumb1 instruction, and this
could not be assembled. The generated object file contained this,
resulting in r0 holding SP+8 rather tha SP+1028:
add r0, sp, #1020
add r0, sp, #8
This function looked like it could have caused miscompilations for
other combinations of registers and offsets (though I don't think it is
currently called with these), and the heuristic it used did not match
the emitted code in all cases.

Don't make assumptions about the name of private global variables.
Private variables are can be renamed, so it is not reliable to make

The name is also dropped by the assembler before getting to the

decision (var name) and how the linker makes a decision (section it is
in).

Don't make assumptions about the name of private global variables.
Private variables are can be renamed, so it is not reliable to make
decisions on the name.
The name is also dropped by the assembler before getting to the

Change order of tablegen generated fast-isel instruction code to be
based on instruction complexity
The order that tablegen fast-isel instruction code is generated is
currently based on the text of the predicate (using string
less-than). This patch changes this to instead use the instruction
complexity. Because the complexities are not unique a C++ multimap is
used instead of a map.
This fixes the problem where code with no predicate always comes out
first (the empty string always compares as less than all other
strings) thus making the code with predicates dead code. See the FMUL
code in PPCFastISel.cpp for an example. It also more closely matches
the normal codegen ordering. Some error checking in the tablegen
fast-isel code is fixed as well.

llvm-cov: Sink some reporting logic into CoverageMapping
This teaches CoverageMapping::getCoveredFunctions to filter to a
particular file and uses that to replace most of the logic found in
llvm-cov report.

X86: use getConstant rather than getTargetConstant behind BUILD_VECTOR.
getTargetConstant should only be used when you can guarantee the instruction
selected will be able to cope with the raw value. BUILD_VECTOR is rather too
generic for this so we should use getConstant instead. In that case, an
instruction can still consume the constant, but if it doesn't it'll be
materialised through its own round of ISel.
Should fix PR21352.

IR: Rewrite uniquing and creation of MDString
Stop using `Value::getName()` to get the string behind an `MDString`.
Switch to `StringMapEntry<MDString>` so that we can find the string by
its coallocation.

CodeGen: assert an instruction is being inserted with the correct iterator.
When "MBB->Insert(It, ...)" is called, we want It to be pointing inside the
correct basic block. No actual failures at the moment, but it's caused problems
before.
