Swap optimizations when inlining

When we optimize a function we run:
1. Constant folding
2. Instruction simplifier
3. Dead code elimination

Make the inliner use the same order of optimizations.

Improvements are small but noticeable. Locally, Pixel 5 speed compile:
 * System server: -7.8KB (-0.02%)
 * SysUIGoogle: -3.9KB (-0.01%)
 * AGSA: -113KB (-0.03%)

Test: art/test/testrunner/testrunner.py --host --64 --optimizing -b
