a5aa63a456 Fix some assembler generating scripts for better unification
Some of these scripts would recognise an output parameter if it looks
like a file path.  That works both in both the classic and new build
schemes.  Some fo these scripts would only recognise it if it's a
basename (i.e. no directory component).  Those need to be corrected,
as the output parameter in the new build scheme is more likely to
contain a directory component than not.

1ea8ae5090 poly1305/asm/poly1305-*.pl: flip horizontal add and reduction.
Formally only 32-bit AVX2 code path needs this, but I choose to
harmonize all vector code paths.

bdbd3aea59 Consistently use arm_arch.h constants in armcap assembly code.
Most of the assembly uses constants from arm_arch.h, but a few references to
ARMV7_NEON don't. Consistently use the macros everywhere.

1457731221 poly1305/asm/poly1305-armv4.pl: replace ambiguous instruction.
Different assembler versions disagree on how to interpret #-1 as
argument to vmov.i64, as 0xffffffffffffffff or 0x00000000ffffffff.
So replace it with something they can't disagree on.
