ARM: Workaround cs2007q3 compiler bug for NEON registers clobber list

128-bit registers "qX" are incorrectly handled in inline assembly
clobber list for codesourcery cs2007q3 gcc toolchain. Only the
first 64-bit half is saved and restored by gcc. Changing clobber
list to use only 64-bit register aliases can solve this problem.
For example, 128-bit register q0 is mapped to two 64-bit
registers d0 and d1, q1 is mapped to d2 and d3, etc.
