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.

lookup, if parsing failed, we did not restore the lexer state properly, and
eventually crashed. This change ensures that we always consume all the tokens
from the new token stream we started to parse the name from inline asm.

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.

This should probably be replaced with build infrastructure support for
a platform-specific canonical Python include path, but for now it should
restore the FreeBSD buildbot.

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.

lldb_private::Debugger was #including some "lldb/API" header files which causes tools (lldb-platform and lldb-gdbserver) that link against the internals only (no API layer) to fail to link depending on which calls were being used.
Also fixed the current working directory so that it gets set correctly for remote test suite runs. Now the remote working directory is set to: "ARCH/TESTNUM/..." where ARCH is the current architecture name and "TESTNUM" is the current test number.
Fixed the "lldb-platform" and "lldb-gdbserver" to not warn about mismatched visibility settings by having each have their own exports file which contains nothing. This forces all symbols to not be exported, and also quiets the linker warnings.

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.

Summary:
- Stop to try to rebuild llvm on each invocation by removing the invalid library entry libLLVMArchive.a which no longer exists.
- Remove the useless ranlib invocation. "libtools -static" automatically takes care of the archive table of content.

Separate ELF note implementations were introduced for core files and
GNU build-id. Move the more general one from elf-core to ObjectFileELF
and use it for build-id as well.
