comparing 140_fcs against 140_01b3 highlights poor performance on 140_01b3.

To reproduce :

Bring over J2Dbench testsuite.
Set JAVA_HOME to JDK.
run gnumake run.

This brings up the console where modifications can be made to the tests.
only select DrawImage tests. In these options only select the following options
20X20, ARGB , No Scaling, and Bitmask.
(alternatively just load the pref file attached, file -> load file)

increase the number of iterations to 15 also in the global options.

while running on Sparc 2.8 the following was output :

dairymilk# setenv JAVA_HOME /export/home/j2sdk1.4.0_01
dairymilk# cd J2DB*

====================================

The 2nd test here runs much slower on 140_01b3

FCS AVG = 2073
140_01b3 AVG = 260

This is ~ 8 times slower.
Other tests were also poor but this was the worst one.

I also ran this test on Win2000.
FCS AVG = 8000
140_01b3 AVG = 2500
