The recent change to generate type functions for more types with
identity comparisons caused us to generate some unnecessary functions,
and even caused a compiler crash on Solaris due to phase ordering.
Avoid this by marking all generated and uncompared struct and array
types as incomparable, so that we don't try to generate type functions
for them.

My previous change to the Cortex-A53 scheduler resulted in a 13% regression on a
proprietary benchmark. This turned out to be due to non-optimal scheduling of int
to float conversions. This patch separates int to FP transfers from int to float
conversions based on experiments to determine the best schedule. As a result of
these tweaks the performance of the benchmark improves by 20%.
