A return statement is elided from MacroAssembler::jump_cc(Assembler::Condition,
AddressLiteral) by devirtualize, causing operation to run into the following function (in this case
''MacroAssembler::verify_oop(RegisterImpl*, char const*)").

See Volker's explanation: http://mail.openjdk.java.net/pipermail/hotspot-dev/2014-April/013602.html

Passing -fno-devirtualize for macroAssembler_x86.o should fix it.
