Keith Randall c2d373d5d1 cmd/compile: allow 128-bit values to be spilled
We sometimes use 16-byte load+store to move values around in memory.
In rare circumstances, the loaded value must be spilled because the
store can't happen yet.

In that case, we need to be able to spill the 16-byte value.

Fixes #53454
