[Clang] Adjust assert from Sema::BuildCXXTypeConstructExpr

Currently Sema::BuildCXXTypeConstructExpr asserts that list initialization must
mean we have an InitListExpr as well. We have several cases of valid code the
result in CXXTemporaryObjectExpr in the AST instead for list initialization.
Commit 1ae689c2 seems to indicate that this is not unexpected, although may be a
design issue
