Embarcadero: Fix erroneous interpretation of __CODEGEARC_VERSION__.

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.
