Intel SVML (Short Vector Math Library) requires custom calling conventions, which are different from system ones (especially on Windows). This patch adds SVML-specific calling conventions to LLVM, including enums, parsing/printing and tablegen. The actual usage in vectorizer will be done in follow up patches.
