To compile with llvm integrated assembler.
* Explicitly specify default .align 0.
* Use standard ldmfdlo instruction.
* Before and after gas outputs are identical,
with align 0 sections.
* Objdump showed .text/.data/.bss section alignment
attributes are 2^0 from gas and 2^2 from llvm
assembler. These .S files might be working when
compiled by gas, but llvm assembler's output should
be more correct or conservative.
