Fix PR 4631. The compound initializers of unions were not being evaluated, which
could cause false positives if any the subexpressions had side-effects. These
initializers weren't evaluated because the StoreManager would need to handle
them, but that's an orthogonal problem of whether or not the StoreManager can
handle the binding.

MultiTestRunner: Oops, clang wasn't being substituted properly. This is why the
cxx-using-declaration test case started exhibiting different behavior. It still
needs to be fixed, however...

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77066 91177308-0d34-0410-b5e6-96231b3b80d8

MultiTestRunner: Always use absolute path names for tests.

Also, fix a function name I forgot to update.

Disable this test: cxx-using-declaration.cpp

Something strange is going on here; this test randomly started failing after
unrelated changes to TestRunner.py (even though it runs the same
script).

Argiris or Doug, can one of you investigate?

MultiTestRunner: Validate '&&' at the end of RUN lines.
 - This is just to normalize, these will go away soon hopefully.

Added all the missing '&&'s that have crept in. :)

MultiTestRunner: Explicitly define child environment, the only variable we need
to import is the PATH.

MultiTestRunner.py improvements.
 - Tweak output directories for temp files, derive the temporary base from the
   test's parent directory name, and the test name (instead of the whole path).

MultiTestRunner.py improvements.
 - Not improved: the horribly lousy name. :)

 - Suppress stderr when capturing output.

 - Rewrite which() to do the right PATH search instead of being lazy and
   shelling out to 'which'.

 - On Windows, run scripts as batch files (via 'cmd /c ...').

Change these tests to not depend as much on the name of the input.

Semantic checking for main().

Fix some invalid main() methods in the test suite that were nicely
exposed by the new checks.

Flesh out the QualifierSet API.

Tweak svn:ignore

More work on the constant struct builder. We can now convert the struct to a packed struct when necessary.

Some code refactoring per Daniel's feedback.

Whoops, did not mean to check this in.

More work on the constant struct builder. We now try to layout all constant structs but throw away the result.

Template instantiation for static data members that are defined out-of-line.

Note that this also fixes a bug that affects non-template code, where we
were not treating out-of-line static data members are "file-scope" variables,
and therefore not checking their initializers.

More Sema check for constructor's member initializer along
