Refactor code-size reduction estimation methods out of InlineCostAnalyzer and into CodeMetrics.  They
don't use any InlineCostAnalyzer state, and are useful for other clients who don't necessarily want to use
all of InlineCostAnalyzer's logic, some of which is fairly inlining-specific.

No intended functionality change.

Add an elf-dumper utility.

- Output format and some of the code stolen from macho-dump.
- Somewhat incomplete and probably buggy.
- Comes with a very basic test.
