- 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).

nice to still have the assert, but we don't have any API call for the
unpadding size of a type yet.

to use a wide enough type. This might be wider than the "single
element"'s type in the presence of padding bit-fields.
- Darwin x86_32 now passes the first 1k ABI tests with bit-field
generation enabled.

- Small structures are returned in a register if:
1. They fit nicely in a register.
2. All fields fit nicely in a register.

- We now pass the first 5000 ABITests if unions are disabled.

- Current return-arguments-32 status is: 1 out of 1000 failures (-7)
- Also, vectors inside "single element structs" require special
handling.

- This is an ABI incompatiblity, but this is not likely to be a huge
deal in practice. For now we at least generate self consistent code
instead of crashing.
