ENH: -if no compiler has been found, don't test it, and also remove the compiler
information file again. This makes optionally enabling a language work
better.

- The short-hand forms do not document the NO_* options.
- CMake 2.4 and 2.6.0 accepted them accidentally, but also
treated the options as paths.
- Now the options are accepted but do not become paths.
- The CMAKE_PREFIX_PATH and similar variables have both
environment and CMake cache versions.
- Previously the environment value was checked before the
cache value.
- Now the cache value is favored because it is more specific.
- Hints are searched after user locations but before system locations
- The HINTS option should have paths provided by system introspection
- The PATHS option should have paths that are hard-coded guesses
- Locating a header inside a framework often requires globbing
- Previously the glob was <dir>/*/Headers/<name>
- Now the glob is <dir>/*.framework/Headers/<name>
- This is much faster when <dir> is not really a framework dir
- CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE are supposed to specify
whether to find frameworks/appbundles FIRST, LAST, ONLY, or NEVER.
- Previously this affected only the placement of CMAKE_FRAMEWORK_PATH
and CMAKE_APPBUNDLE_PATH with respect to the other path specifiers.
- Now it behaves as documented. The entire search path is inspected for
each kind of program, library, or header before trying the next kind.
- Additionally the ONLY mode is now honored for headers so that users
do not end up with a library in framework and a header from elsewhere.
- In cmFindBase when CheckCommonArgument returns true, set newStyle
- Otherwise if there are no PATHS then the ancient-style compatibility
mode is enabled and the common argument is treated as a path.
- Add each part of the search order in a separate method.
- Collect added paths in an ivar in cmFindCommon.
- Move user path storage up to cmFindCommon and share
between cmFindBase and cmFindPackageCommand.
- Expand user path registry values up in cmFindCommon
- Enables 32-/64-bit registry view for find_package
- Disables registry expansion for paths not specified
with the PATHS argument, which is not expected.
- cmFindBase should search both 32-bit and 64-bit registry views
for FIND_PROGRAM even if CMAKE_SIZEOF_VOID_P is not set.
- Needed because the variable is not available when CMAKE_MAKE_PROGRAM
is to be found.
- The rule hash should use only commands specified by the user.
- No make output (echo and progress) rules should be included.
- No outputs or dependencies need be included. The native build tool
will take care of them.
