RFR 8173715 (rev2): Remove Flat Profiler

hi all,

The FlatProfiler (i.e. -Xprof) has been deprecated in jdk9, and now it’s the time to remove the code and obsolete the -Xprof flag.

Can someone please review the "hotspot/src/cpu/sparc/vm/macroAssembler_sparc.cpp” file to determine whether we still need the three "save_frame_and_mov(0, Lmethod, Lmethod);” calls where the comment said it was needed by -Xprof?

Do we leave those save_frame_and_mov() calls as is (and add comment as to why they are still needed), or can we change them into save_frame() calls?
