This is an extensive refactoring of the Cray compiler wrapper usage.
Using the new compiler wrapper checks, the CrayPrgEnv info files have
been moved from Platform/ to Compiler/.  The adjusted naming convention
allows the compiler-wrapper information files to be loaded for both the
CrayLinuxEnvironment platform when cross-compiling and the Linux
platform if building natively on the Cray compute nodes.  It also
creates a separation of common arguments for compiler id and language
information used to perform the appropriate introspection of implicit
arguments and libraries used by the compiler wrappers based on the
loaded module environment.

- Add TIFF::TIFF imported target
- Document imported target
- Add testcase to test the standard variables and the imported
  target

Also:

- Add TIFF_INCLUDE_DIRS to match common practice
- Update documentation generally, including documenting
  TIFF_INCLUDE_DIRS

If multiple input files are provided then the destination must be a
directory.  If only one input file is provided then destination may be
either a file or directory.

e76ee2c0 iOS: Fix framework resource directory layout (#15848)

As per the following link:

  http://docwiki.embarcadero.com/RADStudio/Seattle/en/Example_of_CODEGEARC_VERSION_Macro

The major/minor versions must be decoded as a hex string, while the patch
version must be decoded as a normal decimal string.

As an example, C++ Builder XE 8.1's bcc32.exe sets this macro to 0x070189C9.
The file version of bcc32.exe is 7.1.5570.35273.  Therefore, the correct
interpretation to COMPILER_VERSION would be 7.1.35273.

This test helps catch errors in compiler identification.

The CMAKE_CXX_COMPILER_ID and CMAKE_C_COMPILER_ID variables are set to
"Borland" for older versions of the compiler.  Newer CodeGear/Embarcadero
compilers will have those variables set to "Embarcadero".  Search for lines of
code referencing both the variable name and Borland to be sure that they also
refer to Embarcadero.
