[dev.ssa] cmd/compile: implement the following for SSA on ARM
- generic Ops: Phi, CALL variants, NilCheck
- generic Blocks: Plain, Check
- 32-bit arithmetics
- CMP and conditional branches
- load/store
- zero/sign-extensions (8 to 16, 8 to 32, 16 to 32)
Progress on SSA backend for ARM. Still not complete. Now "errors"
package compiles and tests passed.
Updates #15365.
