x86: Handle unsupported static rounding in vcvt[u]si2sd in 32-bit mode
Update x86 disassembler to handle the unsupported static rounding in vcvt[u]si2sd in 32-bit mode. gas/ PR binutils/23655 * testsuite/gas/i386/evex.d: Updated. opcodes/ PR binutils/23655 * i386-dis-evex.h: Replace EXxEVexR with EXxEVexR64 for vcvtsi2sd%LQ and vcvtusi2sd%LQ. * i386-dis.c (EXxEVexR64): New. (evex_rounding_64_mode): Likewise. (OP_Rounding): Handle evex_rounding_64_mode.
