Committed as r196116.
The issue in PR56350 is two-fold. First, fix_loop_structure mishandles
latch edge computation (ugh). Second, RTL if-conversion, when merging
a latch block into sth else ends up generating stale latch block
references.
The following two patches cure that, adding some basic latch block
checking.

Hi all,
This patch uses the new ARMv8 AArch32 vsel instruction to implement

For example, an instruction of the form:
