non-trivial special members for varargs calls.

Fix CXXRecordDecl::forallBases to not look through bases which are dependent
and defined within the current instantiation, but which are not part of the
current instantiation. Previously, it would look at bases which could be
specialized separately from the current template.

Reapply a subset of r167567 to clean up Darwin-specific code for invoking gcc.

Unlike my previous attempt at this, this patch leaves intact the check for
whether clang can handle the input file type, and for non-Darwin toolchains it
will invoke gcc for things it cannot handle. For Darwin toolchains, the
behavior reported in pr14338 still occurs with this patch, but that is a
definite improvement from what happens currently, where it just crashes with
an assertion failure.

Check that we don't warn on this testcase. This is basically a test that
Decl::isUsed checks the attribute. If the function had a body just the check
is DeclMustBeEmitted would be sufficient.

[analyzer] Fix a crash reported in PR 14400.

The AllocaRegion did not have the superRegion (based on LocationContext)
as part of it's hash. As a consequence, the AllocaRegions from
different frames were uniqued to be the same region.

[analyzer] SATestBuild.py: allow make builds to disable parallelization

Before, SATestBuild unilaterally added '-j<n>' to every project built with

allows a project to explicitly be marked '-j1'.
