cpu/or1k: Add support for orfp64a32 spec
This patch adds support for OpenRISC 64-bit FPU operations on 32-bit cores by using register pairs. The functionality has been added to OpenRISC architecture specification version 1.3 as per architecture proposal 14[0]. For supporting assembly of both 64-bit and 32-bit precision instructions we have defined CGEN_VALIDATE_INSN_SUPPORTED. This allows cgen to use 64-bit bit architecture assembly parsing on 64-bit toolchains and 32-bit architecture assembly parsing on 32-bit toolchains. Without this the assembler has issues parsing register pairs. This patch also contains a few fixes to the symantics for existing OpenRISC single and double precision FPU operations.
