commit 522f9205c9ed5e1ed23389e2c2b186de352835df
Author: Raymond Toy <rtoy at google.com>
Date:   Tue Mar 27 14:22:11 2012 -0700

    Set the generator costs for the complex multiply vops to be the number
    of instructions.  This gives the sse3 complex multiply vop a chance to
    be used if SSE3 is available.  (The user needs to :SSE3 to *FEATURES*
    for this to work.  The core of CMUCL only assumes SSE2 is available.)
