Kconfig: remove the CONFIG_CC_ALIGN_* options
I don't see any use case for the CONFIG_CC_ALIGN_* options: - they are only available if EMBEDDED - people using EMBEDDED will most likely also enable CC_OPTIMIZE_FOR_SIZE - the default for -Os is to disable alignment In case someone is doing performance comparisons and discovers that the default settings gcc chooses aren't good, the only sane thing is to discuss whether it makes sense to change this, not through offering options to change this locally.

-config CC_ALIGN_LABELS

- Align all branch targets to a power-of-two boundary, skipping

- make code slower, because it must insert dummy operations for
