Fix invalid const atomic builtin accesses.

Clang fixed a signature issue with builtin atomic functions accidentally
allowing const-qualified arguments. This change removes the invalid
const qualifiers from those calls. The error message looks like:
"address argument to atomic builtin cannot be const-qualified"

Bug: http://b/110779387
Test: Builds with new compiler.
