End-end test with no integrated assembly should be added

This fixes the following unit tests:

FuzzerDictionary.ParseOneDictionaryEntry
FuzzerDictionary.ParseDictionaryFile

The issue appears to be mixing non-ASan-ified code (LibFuzzer) and
ASan-ified code (the unittest) as the tests would pass fine if
everything was built with ASan enabled.

I believe the issue is that different implementations of std::vector<>
are being used in LibFuzzer and outside LibFuzzer (in the unittests).
For Libcxx (I've not seen the issue manifest for libstdc++) we can disable
the ASanified std::vector<> by definining the ``_LIBCPP_HAS_NO_ASAN`` macro.
Doing this fixes the tests on OSX.

This is the next step towards being able to write PDBs.
MemoryBuffer is immutable, and StreamInterface is our replacement
which can be any combination of read-only, read-write, or write-only
depending on the particular implementation.

The one place where we were creating a PDBFile (in RawSession) is
updated to subclass ByteStream with a simple adapter that holds
a MemoryBuffer, and initializes the superclass with the buffer's
array, so that all the functionality of ByteStream works
transparently.

llvm-svn: 272370

This adds method and tests for writing to a PDB stream.  With
this, even a PDB stream which is discontiguous can be treated
as a sequential stream of bytes for the purposes of writing.

 - The intended use of this was just in diagnostics, so we shouldn't pay the
   cost of reading these all the time.

 - This will avoid including the full output of each command in tests which
   fail, but the most important use case for this was to gather the output of
   the specific command which failed.

The test case is not great espicially because it is still cumbersome to
run the regalloc pass with run-pass. (We miss a bunch of initiliazier to
be properly implemented.)

Thanks to Matthias Braun for spotting this.

Previously we could run only one machine pass with the run-pass option.
With that patch, we can now specify several passes with several run-pass
options (or just one option with a list of comma separated passes) and
llc will build the related pipeline.
This is great to test the interaction of two passes that are not
necessarily next to each other in the pipeline, or play with pass
ordering.
Now, we should be at parity with opt for the flexibility of running
passes.

Note: I also moved the run pass option from CommandFlags.h to llc.cpp
because, really, this is needed only there!

This was using extract_subreg sub0 to extract the low register

Prior to this patch, we used argument/global stratified attributes in
order to note that a value could have come from either dereferencing a
global/arg, or from the assignment from a global/arg.

Now, AttrUnknown is placed on sets when we see a dereference, instead of
the global/arg attributes. This allows us to be more aggressive in the
future when we see global/arg attributes without AttrUnknown.

[cpu-detection] [amdfam10] Return barcelona, and amdfam10 for all other
subtypes. Address Bug 28067.

Along with the refactoring of Host.cpp, getHostCPUName() was modified to
return more precise types for CPUs in amdfam10.
However, callers of getHostCPUName() do string matching on type, so this
cannot be modified.
Currently there is support in the x86 backend for barcelona.
For all other subtypes the assumed return value is amdfam10.

Fix: getHostCPUName() returns barcelona subtype and amdfam10 for all
others. This can be extended further when support for the other subtypes
is added.
