NFC: Move TypeList implementation up the file

This will make it possible for more code to use it.

[GlobalISel] Don't form zero/sign extending loads for atomics.

For importing patterns, we only support matching G_LOAD, not G_ZEXTLOAD or

[AArch64][GlobalISel] Create a new minimal combiner pass just for -O0.

We never bothered to have a separate set of combines for -O0 in the prelegalizer
before. This results in some minor performance hits for a mode where performance
isn't a concern (although not regressing code size significantly is still preferable).

This also removes the CSE option since we don't need it for -O0.

Through experiments, I've arrived at a set of combines that gets the most code
size improvement at -O0, while reducing the amount of time spent in the combiner
by around 35% give or take.

[mlir][vector] Fix warning

Previous change caused another warning in some build configuration:
