[ARM] Fix PR89222
The GCC optimizer can generate symbols with non-zero offset from simple
if-statements. Bit zero is used for the Arm/Thumb state bit, so relocations
with offsets fail if it changes bit zero and the relocation forces bit zero
to true. The fix is to disable offsets on function pointer symbols.

* config/arm/arm.md (movsi): Use targetm.cannot_force_const_mem
to decide when to split off a non-zero offset from a symbol.
* config/arm/arm.c (arm_cannot_force_const_mem): Disallow offsets
in function symbols.
