This reverts commit 9c319d5bb40785c969d2af76535ca62448dfafa7.
Some issues were discovered with the bootstrap builds, which
seem like they were caused by this commit. I'm reverting to investigate.

[AArch64] Update generic sched model to A510
Refresh of the generic scheduling model to use A510 instead of A55.
Main benefits are to the little core, and introducing SVE scheduling information.

Refresh of the generic scheduling model to use A510 instead of A55.
Main benefits are to the little core, and introducing SVE scheduling information.
Changes tested on various OoO cores, no performance degradation is seen.

[DAG] Combine insert(shuffle(load), load, 0) into a single load
Given an insert of a scalar load into a vector shuffle with mask
u,0,1,2,3,4,5,6 or 1,2,3,4,5,6,7,u (depending on the insert index),
it can be more profitable to convert to a single load and avoid the
shuffles. This adds a DAG combine for it, providing the new load is
still fast.
