[m-rev.] For review: Implement support for threadscope profiling.

[Paul Bone]

These tests fail in asm_fast.gc.profdeep in both workspaces, a clean one and
the one with my changes.  This is tested on goofy.

general/string_format_test_2
general/string_format_test_3
hard_coded/solver_default_eq_cmp

Shall I file a bug and look at them at sometime in the future?

Thanks.
