Sparc: improve CPU register dump

Common:
 * Remove unnecessary 0x prefix
 * Print %y
 * Fix NZVC flag print order to match CPU bit order

Sparc64 specific:
 * Print registers without line wrapping
 * Print %f40-%f63
 * Pretty print CCR flags
 * Print %fsr and %fprs in full precision
 * More consistent formatting
