fortran: Testsuite, fix different type naming across compilers.

Gfortran and ifort have different names for data types.  Encapsulate
type names in a library to increase number of supported compilers.
gfortran -4.2 : int4
gfortran>=4.3 : integer(kind=4)
ifort         : INTEGER(4)

2016-04-18  Bernhard Heckel  <bernhard.heckel@intel.com>

gdb/testsuite/Changelog:
	* gdb.fortran/common-block.exp: Use type naming defined in lib fortran.
	* gdb.fortran/derived-type.exp: Use type naming defined in lib fortran.
	* gdb.fortran/multi-dim.exp: Use type naming defined in lib fortran.
