Allow redirecting disassembly and deoptimization traces into a file.

Browse Source 
This is controlled by two flags:

--redirect_code_traces
--redirect_code_traces_to=<filename>

When redirection is enabled but --redirect_code_traces_to is not specified traces are written to a file code-<pid>-<isolate>.asm. This mangling scheme matches hydrogen.cfg and allows easy discovery of compilation artifacts in a multi-V8 environment (e.g. when compilation is traced from inside Chromium).

D8 defines --redirect_code_traces_to=code.asm similar to hydrogen.cfg redirection.
