runtime, sync/atomic: use NOFRAME on arm
This replaces frame size -4 with the NOFRAME flag in arm assembly.
This was automated with:
sed -i -e 's/\(^TEXT.*[A-Z]\),\( *\)\$-4/\1|NOFRAME,\2$0/' $(find -name '*_arm.s')
Plus three manual comment changes found by:
grep '\$-4' $(find -name '*_arm.s')
The go binary is identical before and after this change.
