Temporary remove "at least 8 byte alignment" code from x86
2018-07-04 Denys Vlasenko <dvlasenk@redhat.com>
* config/i386/dragonfly.h: (ASM_OUTPUT_MAX_SKIP_ALIGN):
Use a simpler align directive also if MAXSKIP = ALIGN-1.
* config/i386/gas.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Likewise.
* config/i386/lynx.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Likewise.
* config/i386/netbsd-elf.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Likewise.
* config/i386/i386.h (ASM_OUTPUT_MAX_SKIP_PAD): Likewise.
* config/i386/freebsd.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Remove "If N
is large, do at least 8 byte alignment" code. Add SUBALIGN_LOG
define. Use a simpler align directive also if MAXSKIP = ALIGN-1.
* config/i386/gnu-user.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Likewise.
* config/i386/iamcu.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Likewise.
* config/i386/openbsdelf.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Likewise.
