Tim Northover 463a5f24d1 ARM: correctly determine final tBX_LR in Thumb1 functions ...

The changes caused by folding an sp-adjustment into a "pop" previously
disrupted the forward search for the final real instruction in a
terminating block. This switches to a backward search (skipping debug
instrs).

This fixes PR18399.

Patch by Zhaoshi.
