Computed styles: Drop uncommon extension blocks.
They were a space saving feature, but they became largely
redundant with computed style sharing. They also made the
code complex and buggy in many places. E.g. the cascade,
inheritance / composition, and intial values all needed to
behave corretly when they, or their parent, had or didn't
have an uncommon block.
Also, only the uncommon block was really used.
