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]
