Follow-up to r353959 and r368070: do the same for other architectures. arm32 already seems to use its own .fnstart/.fnend directives, which appear to be ARM-specific variants of the same thing. Likewise, MIPS uses .frame directives. Reviewed by: arichardson Differential Revision: https://reviews.freebsd.org/D27387
