[Patch ARM] PR 40887 - Fix return to use blx.

[Ramana Radhakrishnan]

Hi, 

This patch fixes PR target/40887 by disabling the call_mem patterns for
arch > armv5te. This allows the correct generation of blx instructions
for armv5te onwards for indirect calls.

Tested with no regressions on qemu for Cortex A8 for ARM and Thumb2.

Ok to commit on trunk ?

cheers
Ramana
