Request for review(XS): 7013812: C1: deopt blob too far from patching stub

[Igor Veresov]

access_filed_patching and load_klass_patching stubs are using 
effectively a bp instruction to jump to deopt blob. This limits the 
distance between the deopt blob and these stub to 2^20, which is not 
enough. Since this situation could become possible also with a 32bit VM 
(the distance is only 1M), I decided to always use long jumps.
