gas: fix CBCOND diagnostics for invalid immediate operands.

This patch fixes two problems in the SPARC assembler:

- The diagnostic message

  Error: Illegal operands: Immediate value in cbcond is out of range.

  is incorrectly issued for non-CBCOND instructions that feature a
  simm5 immediate field, such as MPMUL, MONTMUL, etc.

- When an invalid immediate operand is used in a CBCOND
  instruction, two redundant error messages are issued to the
  user, the second due to a stale fixup (this happens since
  commit 85024cd8bcb93f4112470ecdbd6c10fc2aea724f).

Some diagnostic tests for the CBCOND instructions are also
included in the patch.

Tested in both sparc64-linux-gnu and sparcv9-linux-gnu targets.
