RFR 8191985: Tlab refills for ARM

[Edward Nevill]

Hi,

I have built and tested this on a Samsung Chromebook (armv7l).

The tests I ran were jtreg hotspot tests patched vs original in three configurations, default gc (g1gc), parallelgc and serialgc. The results in all cases were identical before and after patching.

Default gc (g1gc): passed: 1,435; failed: 9; error: 116
ParallelGC: passed: 1,331; failed: 8; error: 112
SerialGC: passed: 1,326; failed: 7; error: 112

Patch looks good to me.

All the best,
Ed.
