Various patterns use "register_operand" "l" (or "=l") although those
patterns are only created refering to LR_REGNO directly. This patch

Many places still use 65 instead of the symbolic constant LR_REGNO. This

I didn't read all code :-) )

This patch adds legitimize_address_displacement hook so that stack accesses
with large offsets are split into a more efficient sequence. Unaligned and
TI/TFmode use a 256-byte range, byte and halfword accesses use a 4KB range,
wider accesses use a 16KB range to maximise the available addressing range
and increase opportunities to share the base address.
