Step 2 of stream-lining parameter parsing - do parameter validity checks in parser - two passes instead of multiple (and theoretically quadratic) passes when checking parameters - removes the need for OKEY and some ONONAME nodes in those passes This removes allocation of ~123K OKEY (incl. some ONONAME) nodes out of a total of ~10M allocated nodes when running make.bash, or a reduction of the number of alloacted nodes by ~1.2%.

Use The fmt internal buffer for character formatting instead of the pp Printer rune decoding buffer. Uses an uint64 instead of int64 argument to fmt_c and fmt_qc for easier range checks since no valid runes are represented by negative numbers or are above 0x10ffff. Add range checks to fmt_c and fmt_qc to guarantee that a RuneError character is returned by the functions for any invalid code point in range uint64. For invalid code points in range utf8.MaxRune the used utf8 and strconv functions already return a RuneError.

Remove check for %p and %T in printValue. These verbs are not recursive and are handled already in printArg which is called on any argument before printValue. Format the type string for %T directly instead of invoking the more complex printArg with %s on the type string. Decouple the %T tests from variables declared in scan_test.go.

The type information for a method includes two variants: a func without the receiver, and a func with the receiver as the first parameter. The former is used as part of the dynamic interface checks, but the latter is only returned as a type in the reflect.Method struct. Instead of computing it at compile time, construct it at run time with reflect.FuncOf. Using cl/20701 as a baseline, cmd/go: -480KB, (4.4%) jujud: -5.6MB, (7.8%) For #6853.

Remove method type information for pruned methods from any program that does not reflect on methods. This can be a significant saving: addr2line: -310KB (8.8%) A future update might want to consider a more aggressive variant of this: setting the Type and Func fields of reflect.Method to nil for unexported methods. That would shrink cmd/go by 2% and jujud by 2.6% but could be considered an API change. So this CL sticks to the uncontroversial change. For #6853.

CL 14603 attempted to preserve the callee-save registers for the darwin/arm runtime initialization routine, but I believe it wasn't sufficient and resulted in the crash reported in issue Saving and restoring the registers on the stack the same way linux/arm does seems more obvious and fixes #14778, so do that. Even though #14778 is not reproducible on darwin/arm64, I applied a similar change there, and to linux/arm64 which obeys the same calling convention. Finally, this CL is a candidate for a 1.6 minor release for the same reason CL 14603 was in a 1.5 minor release (as CL 16968). It is small and only touches the iOS platforms and gomobile on darwin/arm is currently useless without it.
