RFR 8004128: NPG: remove stackwalking in Threads::gc_prologue and gc_epilogue code

[Coleen Phillimore]

I created another webrev with the better version of webrev (with source 
file navigation) which makes this much easier to read.

open webrev at http://cr.openjdk.java.net/~coleenp/8004128_2/

Thanks!
