6944033: RFE: add PCM_FLOAT support
has caused the regreesion test to fail to compile.

AudioFloatConverter.PCM_FLOAT was removed in that changeset and causing the test failing to compile. The tests probably need update.

test/javax/sound/midi/Gervill/AudioFloatConverter/ToFloatArray.java:50: cannot find symbol
                    AudioFloatConverter.PCM_FLOAT,
                                       ^
  symbol: variable PCM_FLOAT
