runtime: use NOFRAME on mips and mips64

This replaces frame size -4/-8 with the NOFRAME flag in mips and
mips64 assembly.

This was automated with:

sed -i -e 's/\(^TEXT.*[A-Z]\),\( *\)\$-[84]/\1|NOFRAME,\2$0/' $(find -name '*_mips*.s')

Plus a manual fix to mkduff.go.

The go binary is identical on both architectures before and after this
change.
