RFR: JDK-8251470: Add a development option equivalant to OptoNoExecute to C1 compiler

[Kazunori Ogata]

Hi,

May I get review for JDK-8251470: Add a development option equivalant to 
OptoNoExecute to C1 compiler?

This patch adds a development option to compile a method with C1 and print 
disassembly of the generated native code, but to skip execution of the 
generated code, in the same manner as OptoNoExecute option does in C2.

Log-based debugging is useful to support a new processor.  In C1, the 
existing options BailoutAfterHIR and BailoutAfterLIR can be used if 
printing HIR/LIR is sufficient.  However, there is no way to print 
disassembly of the generated code because these existing options quit 
compilation before generating native code.  So this issue proposes a new 
option for this purpose.
