[patch] Arm FPA stfpls

[Paul Brook]

The attached patch fixes a bug introduced with the Arm unified assembly syntax 
changes.

The "stfpls" instruction is not parsed correctly. This mnemonic matches both 
an infixed and suffixed instructions (stfs pl and stfp ls respectively).

The problem is that when a conditional suffix matches but is disallowed, the 
parser returnes failure instead of trying an conditional infix.

Tested with cross to arm-none-eabi.
Ok?
