Add LTO support

The patch reuses the configuration for LTO from ix86 and adds the
aarch64 architecture to the list of supported COFF headers.

	* config/aarch64/cygming.h (TARGET_ASM_LTO_START): New.
	(TARGET_ASM_LTO_END): Likewise.
	* config/i386/cygming.h (TARGET_ASM_LTO_START): Update.
	(TARGET_ASM_LTO_END): Likewise.
	* config/i386/i386-protos.h (i386_pe_asm_lto_start): Delete.
