For a long time now the compiler has permitted printing a symbol with the %c operator, but for some reason we've never permitted symbol+offset. This patch fixes this omission and also makes the compiler slightly more friendly to users of ASM statements by not generating an ICE when it can't handle an expression. Tested on arm-eabi and installed on trunk. This is not a regression, so I don't propose to back-port it to older compilers (though doing so would most-likely be trivial).
