[13]RFR: 8226627: assert(t->singleton()) failed: must be a constant

[Jamsheed]

Hi,

Request for review.

with 8212043, new nodes were added for MaxFD,MinFD, from mails it seems 
like constant folding part was not implemented and was partially 
disabled here[1].

implemented constant folding for MaxFD, MinFD

testing: mach1-5, mach1-5(-XX:CompileThresholdScaling=0.1) mach5 
(hs-precheckin-comp).

Best regards,
