8314319: LogCompilation doesn't reset lateInlining when it encounters a failure.

[satyenme]

Backporting JDK-8314319: LogCompilation doesn't reset lateInlining when it encounters a failure. Fixes issue where compilation encounters a failure after it processes '<late_inline>' tag, and, in cases where the C2 compiler retries after tweaking options it omits subsume_load. Adds test. Ran GHA Sanity Checks, local Tier 1 and 2 tests. Patch is clean.
