Instead of asking the user to specify a single file to output coverage
info and defaulting to STDOUT, llvm-cov now creates files for each
source file with a naming system of: <source filename> + ".llcov".
This is what gcov does and although it can clutter the working directory
with numerous coverage files, it will be easier to hook the llvm-cov
output to tools which operate on this assumption (such as lcov).

This is useful for debugging issues in the BlockFrequency implementation
since one can easily visualize where probability mass and other errors
occur in the propagation.
This is the MI version of r194654.

and emitted per function and CU. Begins coalescing ranges as a first
class entity through debug info. No functional change.

Each line stores all the blocks that execute on that line, instead of
only storing the line counts previously accumulated. This provides more
information for each line, and will be useful for options in enabling
block and branch information.

Added GCOVEdge which are simple structs owned by the GCOVFunction that
stores the source and destination GCOVBlocks, as well as the counts.
Changed GCOVBlocks so that it stores a vector of source GCOVEdges and a
vector of destination GCOVEdges, rather than just the block number.
Storing the block number was only useful for knowing the number of edges
and for debug info. Using a struct is useful for traversing the edges,
especially back edges which may be needed later.

PPCScoreboardHazardRecognizer was a subclass of ScoreboardHazardRecognizer
which did only one thing: filtered out nodes in EmitInstruction for which
DAG->getInstrDesc(SU) returned NULL. This used to be the case for PPC pseudo
instructions. As far as I can tell, this is no longer true, and so we can use
ScoreboardHazardRecognizer directly.

Add a helper function getDebugInfoVersionFromModule to return the debug info
version number for a module.
"Verifier/module-flags-1.ll" checks for verification errors.
It will seg fault when calling getDebugInfoVersionFromModule because of the
incorrect format for module flags in the testing case. We make
getModuleFlagsMetadata more robust by checking for error conditions.

Header/cpp file rename to follow immediately - just splitting out the
commits for ease of review/reading to demonstrate that the renaming
changes are entirely mechanical.

MO_JumpTableIndex and MO_ExternalSymbol don't show up on inline asm.
Keeping parts of the old asm printer just to print inline asm to a string that
we then parse back looks like a hack.

The profile file parser needed some tests for its parsing actions.
This adds tests for each of the error messages emitted by the parser.

When a block is unreachable, asking its dom tree descendants should
return the empty set. However, the computation of the descendants
was causing a segmentation fault because the dom tree node we get
from the basic block is initially NULL.
Fixed by adding a test for a valid dom tree node before we iterate.
The patch also adds some unit tests to the existing dom tree tests.

to be a bit more sensible. The public interface now is first followed by
the implementation details.
This also resolves a FIXME to make something private -- it was already
possible as the one special caller was already a friend.
No functionality changed.

eliminateFrameIndex() has been reworked to handle both small & large frames
with either a FP or SP.
An additional Slot is required for Scavenging spills when not using FP for large frames.
Reworked the handling of Register Scavenging.
Whether we are using an FP or not, whether it is a large frame or not,
and whether we are using a large code model or not are now independent.

These are used by MachO only at the moment, and (much like the existing
MOVW/MOVT set) work around the fact that the labels used in the actual
instructions often contain PC-dependent components, which means that repeatedly
materialising the same global can't be CSEed.
With small modifications, it could be adapted to how ELF finds the address of
_GLOBAL_OFFSET_TABLE_, which would give similar benefits in PIC mode there.
