Russ Cox 54198b04db cmd/compile: disallow embed of var inside func
Allowing embedding into []byte inside a func creates an
unfortunate problem: either all calls start with the same
underlying data and can see each other's changes to the
underlying data (surprising and racy!) or all calls start
by making their own copy of the underlying data
(surprising and expensive!).

After discussion on #43216, the consensus was to remove
support for all vars embedded inside functions.

Fixes #43216.
