Detect a COMPILER_ID also for ASM. 

For assembler, the "compiler ID" cannot be detected by "compiling" a
source file, since there is not source file all assemblers understand.
Instead the function CMAKE_DETERMINE_COMPILER_ID_VENDOR() is used to
run the assembler and check its output.
For this the CMAKE_DETERMINE_COMPILER_ID_VENDOR() function had to be
extended so that it creates the run directory if it doesn't exist yet.

In CMakeASMInformation.cmake now also CMAKE_ASM_COMPILER_ID is used
(but there are no such files yet, will come with the support for the
IAR toolchain).
