Request for review(XXS): 6989368: Regression in scimark2.MonteCarlo in jdk7_b112 on Linux

[Igor Veresov]

Thanks to Mark Christiaens for noticing it. And Vladimir for analysis!

ciMethod::instructions_size() returns incorrect value after "6953144: 
Tiered compilation" changes. The method code was merged incorrectly with 
changes for "6978355: renaming for 6961697". code->insts_end() should be 
used instead of code->code_end().

Verified with scimark.

Thanks,
igor
