[Bug gas/818] New: error handling %farg[0-4] registers

[efrias at syncad dot com]

When gas encounters the statement:
    fldws       -4(%r22),%farg0
it issues the error:
    Error: Field out of range [0..31] (-59).
    Error: Invalid operands
similarly for %farg1, %farg2, and %farg3, it issues similar warnings with -58,
-57, and -56 as the constant.

HP's native assembler accepts the statement.  When I disassemble the output of
the native assembler, it converted that statement to:
    fldw -4(,r22),fr4

So it appears %farg0 should be a synonym for %fr4.  As a workaround, I've
modified my code to use %fr[4-7] instead of %farg[0-3] and gas is happy with 
this.

This bug is present in binutils-2.15 and in the binutils-050404 snapshot I just
tested.
