3d94178ab6 GlobalISel: remove "unsized" LLT
It was only really there as a sentinel when instructions had to have precisely
one type. Now that registers are typed, each register really has to have a type
that is sized.

cdce758a72 GlobalISel: cache pointer sizes in LLT
Otherwise everything that needs to work out what size they are has to keep a
DataLayout handy, which is a bit silly and very annoying.

b430a4adda GlobalISel: support loads and stores of strange types.
Before we mischaracterized structs and i1 types as a scalar with size 0 in
various ways.

4951996d06 GlobalISel: implement low-level type with just size & vector lanes.
This should be all the low-level instruction selection needs to determine how
to implement an operation, with the remaining context taken from the opcode
(e.g. G_ADD vs G_FADD) or other flags not based on type (e.g. fast-math).
