* rs6000.c (output_function_profiler): Use .long for a 32-bit

* rs6000.c (output_function_profiler): Use .long for a 32-bit
quantity, fix profile1.C test failure under -fPIC.

* rs6000.c: Add 'u' to many constants to suppress warnings.
(constant_pool_expr_1): Make static.
(rs6000_emit_eh_toc_restore): Remove unused 'r2'.
* rs6000.h: Add 'u' to many constants to suppress warnings.

* rs6000.c (rs6000_emit_load_toc_table): Use LCTOC..1 under AIX
for the start of the TOC, instead of LCTOC..0.
* aix.h (toc_section): Use LCTOC..1 under AIX for the start
of the TOC.
* rs6000.md (load_toc_aix_si): Use LCTOC..1.
(load_toc_aix_di): Use LCTOC..1.

* rs6000.h (LEGITIMIZE_ADDRESS): Turn into a function.
* rs6000.c (rs6000_legitimize_address): New function from
LEGITIMIZE_ADDRESS.  Only use create_TOC_reference on
symbols in the constant pool that really are TOC references.
(print_operand_address): For ELF, write TOC offsets under
-fPIC as subtractions in the insn.
(output_toc): For ELF, define symbols in TOC as normal labels,
to match RTL.
(create_TOC_reference): Use gen_rtx_PLUS rather than gen_rtx.
* rs6000-protos.h (rs6000_legitimize_address): Prototype.
(create_TOC_reference): Prototype only when RTX_CODE is defined.
* rs6000.md (movsi): Only use create_TOC_reference on
symbols in the constant pool that really are TOC references.

* rs6000.h (MACHINE_DEPENDENT_REORG): Don't define.
* rs6000.c (rs6000_reorg): Delete.
* rs6000-protos.h (rs6000_reorg): Delete.
