326ea438bb cmd/compile: rewrite a, b = f() to use temporaries when type not identical
If any of the LHS expressions of an OAS2FUNC are not identical to the
respective function call results, escape analysis mishandles the
implicit conversion, causes memory corruption.

Instead, we should insert autotmps like we already do for f(g()) calls
and return g() statements.

Fixes #46725

9844e4cd7c test: correct type in declbad.go
The test is not about type mismatches and it causes
an extra error to appear.

a5d7c1f45e errchk: allow multiple patterns
// ERROR "pattern1" "pattern2"

means that there has to be one or more
lines matching pattern1 and then excluding
those, there have to be one or more lines
matching pattern2.  So if you expect two
different error messages from a particular
line, writing two separate patterns checks
that both errors are produced.

Also, errchk now flags lines that produce
more errors than expected.  Before, as long as
at least one error matched the pattern, all the
others were ignored.

Revise tests to expect or silence these
additional errors.

8aa9161e47 With the changes to support automatic forward declarations of
type names, gccgo no longer reports redefinition errors for
:=, because it no longer knows at parse time whether the type
has changed.  Adjust this test to not match "redefinition",
and to instead match gccgo's current output.
