[ARM] Add FP handling for MVE lane interleaving

FP16 to FP32 converts can be handled in MVE lane interleaving, much like
the sext/zext lowering we do. This expands the pass with fpext and
fptrunc handling, and basic fp operations allowing more efficient
lowering of fp vectors.

[X86][AMX] Hoist ldtilecfg

The previous code calculated the first ldtilecfg by dominating all AMX registers' def. This may result in the ldtilecfg being inserted into a loop.

This patch try to calculate the nearest point where all shapes of AMX registers are reachable.
