Constrain PowerPC autovectorization to fix bug 15041.

Certain vector operations don't vectorize well with the current
PowerPC implementation.  Element insert/extract performs poorly
without VSX support because Altivec requires going through memory.
SREM, UREM, and VSELECT all produce bad scalar code.

There's a lot of work to do for the cost model before
autovectorization will be tuned well, and this is not an attempt to
address the larger problem.

Fix handling of module imports adding names to a DeclContext after qualified
name lookup has been performed in that context (this probably only happens in
C++).

1) Whenever we add names to a context, set a flag on it, and if we perform
lookup and discover that the context has had a lookup table built but has the
flag set, update all entries in the lookup table with additional names from
the external source.

2) When marking a DeclContext as having external visible decls, mark the
context in which lookup is performed, not the one we are adding. These won't
be the same if we're adding another copy of a pre-existing namespace.
