  -----------
  [RISCV] Add test cases for fli.h and fli.d CodeGen bugs. NFC

We fail to use fli.h for the 2 denormal values.
We use fli.d for some values where the value is larger than a float
can represent due to truncating the exponent to 8 bits without checking
if it fits in 8 bits.

  Log Message:
  -----------
  [RISCV] Add separate lookup tables for fli.h and fli.d.

Use separate lookup tables instead of trying to reuse the fli.s
table.

We were missing the 2 denormal cases for fli.h. We also had an issue
where fli.d was only checking 8 bits of the 11 bit exponent.
