RFR 8150388: Remove SPARC 32-bit support

[harold seigel]

Hi George,

Most of the changes look good.  A few comments:

1. In stubGenerator_sparc.cpp, lines 831-835 should not be deleted, just 
the "&& defined(_LP64)"

    831 #if defined(ASSERT) && defined(_LP64)
    832 __ signx(Rint, Rtmp);
    833 __ cmp(Rint, Rtmp);
    834 __ breakpoint_trap(Assembler::notEqual, Assembler::xcc);
    835 #endif

2. In atomic_solaris_sparc.hpp: remove lines 245 and 372

3. In prefetch_solaris_sparc.inline, remove lines 30 and 63

4. In thread_solaris_sparc.hpp, remove line 67.

Thanks, Harold
