RFR: 8201274: Launch Single-File Source-Code Programs

[Jonathan Gibbons]

Please review an initial implementation for the feature described in
JEP 330: Launch Single-File Source-Code Programs.

The work is described in the JEP and CSR, and falls into various parts:

  * The part to handle the new command-line options is in the native
    Java launcher code.
  * The part to invoke the compiler and subsequently execute the code
    found in the source file is in a new class in the jdk.compiler module.
  * There are some minor Makefile changes, to add support for a new
    resource file.

There are no changes to javac itself.
