            Bug ID: 187479
           Summary: Add --traceLLIntExecution and --traceLLIntSlowPath
                    options.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mark.lam at apple.com

These options are only available if LLINT_TRACING is enabled in LLIntCommon.h.

The details:
1. LLINT_TRACING consolidates and replaces LLINT_EXECUTION_TRACING and LLINT_SLOW_PATH_TRACING.
2. Tracing is now guarded behind runtime options --traceLLIntExecution and --traceLLIntSlowPath.  This makes it such that enabling LLINT_TRACING doesn't means that we'll continually spammed with logging until we rebuild.
3. Fixed slow path LLINT tracing to work with exception check validation.
