Subject: Jib: Fix optimizations for SMT IR changes

Fixes C backend optimizations that were disabled due to changes in the
IR while working on the SMT generation.

Also add a -Oaarch64_fast option that optimizes any integer within a
struct to be an int64_t, which is safe for the ARM v8.5 spec and
improves performance significantly (reduces Linux boot times by 4-5
minutes). Eventually this should probably be a directive that can be
attached to any arbitrary struct/type.

Fixes the -c_specialize option for ARM v8.5. However this only gives a
very small performance improvment for a very large increase in
compilation time however.
