Hi All,

This patch adds new alternatives to the patterns which are affected.  The new
alternatives with the conditional early clobbers are added before the normal
ones in order for LRA to prefer them in the event that we have enough free
registers to accommodate them.

In case register pressure is too high the normal alternatives will be preferred
before a reload is considered as we rather have the tie than a spill.

Tests are in the next patch.

Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.

Ok for master?

Thanks,
Tamar
