aarch64-pe can't fill 16 bytes in section .text
Without commit b66e671854, this: .p2align 4 nop .p2align 3 nop results in an error when coff_frob_section attempts to pad out the section to a 16-byte boundary. Due to miscalculating the pad pattern repeat count, write.c:write_contents attempts to shove 16 bytes of padding into the remaining 4 bytes of the .text section. * config/obj-coff.c (coff_frob_section): Correct fill count. Don't pad after errors.
