Move the construction of ProfilingInfo in the compiler.

This reduces the number of inline caches when the compiler can
statically determine the target is fixed.

The removal of some inline cache profiling also improves performance of
compose scrolling. Jank data for 20 seconds, average of 50
runs:
- For Go Mokey:
    - Before:  ~485 frames drawn / ~17.02% janky frames
    - After:   ~525 frames drawn / ~14.64% janky frames
- For Pixel 8 pro:
    - Before:  ~2433 frames drawn / 1.02% janky frames
    - After:   ~2443 frames drawn / 0.91% janky frames
