 Subject: [PATCH] Reduce nesting of parentheses in conditionals generated by
         * genattrtab.c (write_test_expr): New parameter EMIT_PARENS
         which defaults to true.  Emit an outer pair of parentheses only if
         EMIT_PARENS.  When continuing a chain of && or || (or & or |),
         don't emit parentheses for the right-hand operand.

 gcc/arm generates so many parens it hits a bracket depth limited which is
 enforced by clang. This reduces the number of parens generated and avoids the
 need to increase bracket depth.
 Fixes PR toolchain/53178 properly.
 Remove hack previously needed to build gcc/arm with clang.
 genattrtab.c:1.2 makes this unnecessary.
 Tested by thorpej.
