Allow tracing of optimized methods
This updates the trace instructions to directly dispatch to
opt_send_without_block.  So this should cause no slowdown in
non-trace mode.

To enable the tracing of the optimized methods, RUBY_EVENT_C_CALL
and RUBY_EVENT_C_RETURN are added as events to the specialized
instructions.

Fixes [Bug #14870]
