Define the 'cmake -A' option to set CMAKE_GENERATOR_PLATFORM without having to spell out the whole variable name. We choose the name '-A' for "platform" because '-P' is already taken, and in the common use case the "platform" is actually an architecture (e.g. x64). Teach the RunCMake test infrastructure to use -A to pass the generator platform. Extend the RunCMake.GeneratorPlatform test with a case to verify that the -A option cannot be repeated.

---------------------

|
* The Visual Studio generators for versions 8 (2005) and above
|
|
learned to read the target platform name from a new
|
|
:variable:`CMAKE_GENERATOR_PLATFORM` variable when it is
|
|
not specified as part of the generator name. The platform
|
|
name may be specified on the :manual:`cmake(1)` command line
|
|
with the ``-A`` option, e.g. ``-G "Visual Studio 12 2013" -A x64``.
