ISA string issues with new Zdinx tests #649
Description
The new Zdinx fma tests added by #642 have incorrect RVTEST_ISA and RVTEST_CASE strings, which causes riscof to break.
Some of the tests (like fmadd.d_b1-01.S) have the correct RVTEST_ISA macro ("RV32I_Zfinx_Zdinx"), but the incorrect RVTEST_CASE macro ("//check ISA:=regex(.*I.*D.*)). This should be checking for Zdinx, not D.
Others have both macros wrong. For example, fmadd.d_b8-01.S has RVTEST_ISA("RV32IFD_Zicsr,RV64IFD_Zicsr") and RVTEST_CASE(0,"//check ISA:=regex(.*I.*D.*);def TEST_CASE_1=True;",fmadd.d_b8). Both of these should have Zdinx, not F/D.
These issues result in repeated warnings when compiling and cause riscof to fail:
