Use unified syntax to compile with both llvm and gas.
* Remove useless stab debug info directives .func and .endfunc,
which are not recognized by clang/llvm integrated assembler.
* Replace require8 with REQUIRE8, preserve8 with PRESERVE8.
* Replace LDRNESB with LDRSBNE, LDREQSB with LDRSBEQ, etc.
* Replace VST1 {*.U8} with VST1.8 ..., VLD1 {*.U8} with VLD1.8,
and VMOV with VMOV.I8.
* New assembler output code is identical or equivalent to old gas output.
For example, the 3 references of
LDR r7, =0x80808080
in omxdl/arm_neon/vc/m4p10/src_gcc/armVCM4P10_Average_4x_Align_unsafe_s.S
produced 3 instances of
.word 0x80808080
by llvm integrated assembler but only one by gas.
