The existing library assumed that a stream's length would never
change. This makes some things simpler, but it's not flexible
enough for what we need, especially for writable streams where
what you really want is for each call to write to actually append.

Many times unit tests for different libraries would like to use
the same helper functions for checking common types of errors.
This patch adds a common library with helpers for testing things
in Support, and introduces helpers in here for integrating the
llvm::Error and llvm::Expected<T> classes with gtest and gmock.
Normally, we would just be able to write:
EXPECT_THAT(someFunction(), succeeded());
but due to some quirks in llvm::Error's move semantics, gmock
doesn't make this easy, so two macros EXPECT_THAT_ERROR() and
EXPECT_THAT_EXPECTED() are introduced to gloss over the difficulties.
Consider this an exception, and possibly only temporary as we
look for ways to improve this.

Previously extractors tried to be stateless with any additional
context information needed in order to parse items being passed
in via the extraction method. This led to quite cumbersome
implementation challenges and awkwardness of use. This patch
brings back support for stateful extractors, making the
implementation and usage simpler.

The operator-> implementation comes from iterator_facade_base, so it should
just work given that the iterator has a tested operator*. But r302257 showed
that required careful handling of for the const qualifier. This patch ensures
the fix in r302257 doesn't regress.

This was reported by the ASAN bot, and it turned out to be
a fairly fundamental problem with the design of VarStreamArray
and the way it passes context information to the extractor.
The fix was cumbersome, and I'm not entirely pleased with it,
so I plan to revisit this design in the future when I'm not
pressed to get the bots green again. For now, this fixes
the issue by storing the context information by value instead
of by reference, and introduces some impossibly-confusing
template magic to make things "work".

Instead, we now pass a context memeber through the extraction
process.

r297310 began inserting red zones around allocations under ASan, which
perturbs the alignment of subsequent allocations. Deliberately specify
this in two places where it matters.
Fixes failures when these tests are run under ASan and UBSan together.

After several smaller patches to get most of the core improvements
finished up, this patch is a straight move and header fixup of
the source.
