RFR (L): 7153771: array bound check elimination for c1

[Vladimir Kozlov]

Roland,

In LIR_Assembler::emit_assert() you do "delete[] op->msg();". Is it 
safe? is it possible that op->msg() could be accessed after the call to 
emit_assert()? In C2 we emit instructions 2 times: one to get size and 
second is final emit. Also is it possible that op->msg() == NULL?

Changes look good to me.

Thanks,
Vladimir
