BuiltinFunctions cache, as it can contain dangling pointers.  This fixes
a bunch of valgrind errors on test/CodeGen/builtins.c

1. it wasn't applying to definitions, only declarations, e.g. int x __asm("foo")
2. multiple definitions were conflicting, they weren't getting merged.
3. the code was duplicated in several places.

for such things. Per PR3618, verified that we're getting the right
code generation.

 - 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.

done in sema, and is reflected by the existing PR3258.  In the meantime,
fix PR3682 by disabling a bogus assertion (which doesn't account for + 
operands).

add support for modifiers on named references, like %c[foo].
