RFR(L): 8008407: remove SPARC V8 support

[Christian Thalinger]

src/cpu/sparc/vm/assembler_sparc.hpp:

Can you also remove these:

v9_only, v9_dep, and (if possible) v8_no_cc.

src/cpu/sparc/vm/macroAssembler_sparc.cpp:

Also remove these (now useless) wrappers:

 void MacroAssembler::mult(Register s1, Register s2, Register d) {
 void MacroAssembler::mult(Register s1, int simm13a, Register d) {

src/cpu/sparc/vm/macroAssembler_sparc.inline.hpp:

Could you also get rid of get_pc like in my changes for 8007415:

1) src/cpu/sparc/vm/macroAssembler_sparc.cpp:

-  inc(L4, get_pc(L4) + 2 * BytesPerInstWord); // skip getpc() code + inc + st_ptr to point L4 at call
+  rdpc(L4);
+  inc(L4, 3 * BytesPerInstWord); // skip rdpc + inc + st_ptr to point L4 at call

2) src/cpu/sparc/vm/sparc.ad:

-    __ get_pc(L2);
+    __ rdpc(L2);

src/os_cpu/solaris_sparc/vm/atomic_solaris_sparc.inline.hpp:

Since _Atomic_move_long_v8 is not used anymore you can removed it from:

src/os_cpu/solaris_sparc/vm/solaris_sparc.il
