1645469 - Add profiler sub-categories for SpiderMonkey JITs

Status: RESOLVED FIXED

(Core :: Gecko Profiler, enhancement, P2)

Description

[Ted Campbell [:tcampbell]]

Currently this info is split between "categories" and "implementation" in the profiling. This bug is about adding sub-categories for the various execution modes.

JavaScript
    Other
    Parsing
    JIT Compile (baseline)
    JIT Compile (ion)
    Interpreter
    JIT (baseline-interpreter)
    JIT (baseline)
    JIT (ion)

In the JIT frame sampler, we apply the appropriate category in addition to
the "implementation" field. For JS frames (IS_JS_FRAME), we identify as
either BaselineInterpreter or Interpreter. Note that JS_Other still applies
to various places we enter SpiderMonkey outside of RunScript.

Depends on D79520
