8ee2b4672f ARM: add explicit .arch and .fpu directives to asm.S
This prevents build errors when compiler and assembler default
targets differ.  Ideally each file would declare the highest
level it requires.  This is however not easily possible as it
complicates assembling pre-armv6t2 code in Thumb-2 mode.

HAVE_NEON is used as indicator for ARMv7-A since no other
symbol exists for this and NEON is only available in this
variant.

21c6512542 ARM: remove MUL64 and MAC64 inline asm
Current GCC versions know how to generate these instructions
properly and avoiding inline asm gives better code.  The MULH
function for ARMv5 uses the same instruction and is also not
needed any more.

The MLS64 macro remains since negating an input would normally
not be allowed as it would fail for INT_MIN.  In our uses, the
inputs never have this value and thus negating is safe.

c51695dbf6 ARM: fix MUL64 inline asm for pre-armv6
Prior to ARMv6, the destination registers of the SMULL instruction
must be distinct from the first source register.  Marking the
output early-clobber ensures it is allocated unique registers.

This restriction is dropped in ARMv6 and later, so allowing overlap
between input and output registers there might give better code.
