Add tests for recently introduced asm error checks in vet.
This adds tests for the new warnings about functions that
don't store to their return slot before returning or that
store to SP-relative addresses in or beyond the argument
frame. It also adds a test for leaf function handling on arm,
where the link register is not implicitly saved.

The symbolic names such as NOSPLIT for annotations on the TEXT
directive appeared after vet started checking .s files. This CL tweaks
the regular expression to allow CAPITALS and the symbols | and +
as well as digits in that field, and interprets NOSPLIT as equivalent
to 7 in that field. All magic.
