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.

Crash reported in PR28023 is caused by the fact that non-type template
parameters are found by tag name lookup.  In the code provided in that PR:

template<int V> struct A {
  struct B {
    template <int> friend struct V;
  };
};

the template parameter V is found when lookup for redeclarations of 'struct V'
is made. Latter on the error about shadowing of 'V' is emitted but the semantic
context of 'struct V' is already determined wrong: 'struct A' instead of
translation unit.

The fix moves the check for shadowing toward the beginning of the method and
thus prevents from wrong context calculations.

This change fixes PR28023.

 - 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

   the specific command which failed.

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!

Fix "frame variable" to show all variables defined in functions and any contained lexical blocks, even if they are static variables. 

For code like:

int g_global = 234;
int g_static = 345;
int main(int argc, char **argv)
{                     
    int a = 22333;
    static int g_int = 123;
    return g_global + g_static + g_int + a;
}


If we stop at the "return" statement, we expect to see "argc", "argv", "a" and "g_int" when we type "frame variable" since "g_int" is a locally defined static variable, but we don't expect to see "g_global" or "g_static" unless we add the -g option to "frame variable".
