(print_operand_address): When TARGET_MINIMAL_TOC, use r30 instead of r2 for TOC references.

(print_operand_address): When TARGET_MINIMAL_TOC, use
r30 instead of r2 for TOC references.
(output_prologue): If TARGET_MINIMAL_TOC, and the constant pool
is needed, then setup r30.
(output_toc): When TARGET_MINIMAL_TOC, use .long instead of .tc.
