by the last patch where we'd try to DAG combine our MVT::Other node
oddly.

Similarly, IntervalMap::begin() is almost as expensive as find(), so use find(x)
instead of begin().advanceTo(x);

This makes RegAllocBasic run another 5% faster.

particular, the immediate has 20-bits of value instead of 21. And bit 0 is '0'
always. Going through the BL fixup encoding was trashing the "bit 0 is '0'"
invariant.

Attempt to get the encoding at slightly more correct with this.

Before determining the effect the alignment of base struct will have in the aligment of the sub-struct,
take into account if the sub-struct is packed and its maximum field alignment.
