RFR(S): 8008242: VerifyOops fails on SPARC

[Morris Meyer]

Folks,

Could I get a review of this P2 issue on SPARC?  I had to fix some 
branch relocation issues first, before relaxing the oop verify in 
c1_LIRAssembler_sparc::type_profile_helper() and mem2reg().

This has been tested through JPRT.

Thanks.
