Change all ARM calls into indirect calls.

 ; Show that we know how to translate vpush and vpop.
 
 ; NOTE: We use -O2 because vpush/vpop only occur if optimized. Uses
 ; simple call with double parameters to cause the insertion of
 ; vpush/vpop.
 
 ; REQUIRES: allow_dump
 
 ; Compile using standalone assembler.
