Vector types are not arithmetic types, either. Note that we now ban
...
__real myvec and __imag myvec, since they aren't all that useful (it's
just an identity function) but we might want to use them in more
restricted cases in the future (e.g., "__real mycomplexvec" could
extract the real parts of a vector of complex numbers).

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
...
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

Explictly track tentative definitions within Sema, then hand those
...
tentative definitions off to the ASTConsumer at the end of the
translation unit.
Eliminate CodeGen's internal tracking of tentative definitions, and
instead hook into ASTConsumer::CompleteTentativeDefinition. Also,
tweak the definition-deferal logic for C++, where there are no
tentative definitions.
Fixes <rdar://problem/6808352>, and will make it much easier for
precompiled headers to cope with tentative definitions in the future.
