Improved support for Clang / LLVM EABI.

The installation of CODESYS Code Generator ARM 4.0.1.0 causes a crash at startup on some systems. For this reason, we have released a new version of CODESYS Code Generator ARM that fixes the problem. The previous version is no longer available for download.

• Fixed major bugs relating to atomic operations:
• The usage of 64-bit data types might lead to internal errors about too complex expressions, especially on platforms with additionally reserved registers. The register usage has been optimized for these cases.
• The intrinsic implementation of the atomic TEST_AND_SET operator has been adapted to not use deprecated instructions on ARMv7.
