This lets one build ASan runtime for ARM/Android by running
make -C tools/clang/runtime/ \
  LLVM_ANDROID_TOOLCHAIN_DIR=/path/to/ndk/toolchain

will be represented in the IR as a plain "i32" type.  This causes the
tests to spuriously fail on platforms where int is not a 32-bit type,
or where the ABI requires attributes like "signext" or "zeroext" to
be used.

This patch adds -triple or -target parameters to force those tests
to use the i386-unknown-unknown target.

Many of our tests specify triples that are not built into clang.
In this commit we allow clang to fail loading the triple if we are only
using clang to emit llvm ir.

We need the TTI information for the loop vectorizer.

After every 1000 CFGElements processed, the ExplodedGraph trims out nodes
that satisfy a number of criteria for being "boring" (single predecessor,
single successor, and more). Rather than controlling this with a cc1 option,
which can only disable this behavior, we now have an analyzer-config option,
'graph-trim-interval', which can change this interval from 1000 to something
else. Setting the value to 0 disables reclamation.

The next commit relies on this behavior to actually test anything.

the diagnostics engine now keeps the DiagnosticOptions object alive.

Previously, we only had support for one level of library under lib/,
with the existence of the two-level lib/StaticAnalyzer/* hardcoded in
the top-level CMakeLists.txt. This became a problem with split of
libRewrite into several libraries -- with the same sub-names as the
libraries in lib/StaticAnalyzer/.

Now, we match up anything under lib/ to the corresponding directory
in include/clang/.
