[PATCH, ARM] Fix PR44557, Thumb-1 ICE

Subject: [PATCH, ARM] Fix PR44557, Thumb-1 ICE

Hi, this patch fixes the ICE in PR44557. It now occurs on trunk only under quite specific option conditions, but debugging this PR leaded to quite obvious Thumb-1 fixes.

Also added a simplified testcase, derived from the one on bugzilla. Tested without regressions, okay to commit to trunk?

Thanks,
Chung-Lin
