compiler, runtime: copy string code from Go 1.7 

Add compiler support for turning concatenating strings into a call to
    a runtime function that takes the appropriate number of arguments.
    
    Rename some local variables in mgc0.c to avoid macros that the new
    rune.go causes to appear in runtime.inc.

* This is a slower but "safe" version of the old chartorune
* that works on strings that are not necessarily null-terminated.
*
* If you know for sure that your string is null-terminated,
* chartorune will be a bit faster.
*
* It is guaranteed not to attempt to access "length"
* past the incoming pointer. This is to avoid
* possible access violations. If the string appears to be
* well-formed but incomplete (i.e., to get the whole Rune
* we'd need to read past str+length) then we'll set the Rune
* to Bad and return 0.
*
* Note that if we have decoding problems for other
* reasons, we return 1 instead of 0.
