arch/tile: factor out <arch/opcode.h> header
The kernel code was using some <asm> headers that included a mix of hardware-specific information (typically found in Tilera <arch> headers) and structures, enums, and function declarations supporting the disassembly function of the tile-desc.c sources. This change refactors that code so that a hardware-specific, but OS- and application-agnostic header, is created: <arch/opcode.h>. This header is then exported to userspace along with the other <arch> headers and can be used to build userspace code; in particular, it is used by glibc as part of implementing the backtrace() function. The new header, together with a header that specifically describes the disassembly code (<asm/tile-desc.h> with _32 and _64 variants), replaces the old <asm/opcode-tile*.h> and <asm/opcode_constants*.h> headers. As part of this change, we are also renaming the 32-bit constants from TILE_xxx to TILEPRO_xxx to better reflect the fact that they are specific to the TILEPro architecture, and not to TILE-Gx and any successor "tile" architecture chips.
