OTYPE and OMETHEXPR were missing from OpPrec. So add them with the same precedences as OT{ARRAY,MAP,STRUCT,etc} and ODOT{,METH,INTER,etc}, respectively. However, ODEREF (which is also used for pointer types *T) has a lower precedence than other types, so pointer types need to be specially handled to assign them their correct, lower precedence. Incidentally, this also improves the error messages in issue15055.go, where we were adding unnecessary parentheses around the types in conversion expressions. Thanks to Cuong Manh Le for writing the test cases for #43428. Fixes #43428.
