[ARM] Assembler and disassembler support Dot Product Extension
This patch add assembler and disassembler support for new Dot Product
Extension.
The support can be enabled through the new "+dotprod" extension.
include/
* opcode/arm.h (FPU_NEON_EXT_DOTPROD): New macro.
(FPU_ARCH_DOTPROD_NEON_VFP_ARMV8): New macro.
gas/
* config/tc-arm.c (fpu_neon_ext_dotprod): New variable.
(neon_scalar_for_mul): Improve comments.
(do_neon_dotproduct): New function to encode Dot Product instructions.
(do_neon_dotproduct_s): Wrapper function for signed Dot Product
instructions.
(do_neon_dotproduct_u): Wrapper function for unsigned Dot Product
instructions.
(insns): New entries for vsdot and vudot.
(arm_extensions): New entry for "dotprod".
* doc/c-arm.texi: Document new "dotprod" extension.
* testsuite/gas/arm/dotprod.s: New test source.
* testsuite/gas/arm/dotprod-illegal.s: New test source.
* testsuite/gas/arm/dotprod.d: New test.
