RFR (XS): 8019625: Test compiler/8005956/PolynomialRoot.java timeouts on Solaris SPARCs

[Niclas Adlertz]

Hi all,

Disabled the test for SPARC (the original bug 8005956 only triggers on x86/x64) and reduced the number of iterations so that it takes less time but still triggers.

A review would be much appreciated. 

Kind Regards,
