Add two new calling conventions for runtime calls This patch adds two new target-independent calling conventions for runtime calls - PreserveMost and PreserveAll. The target-specific implementation for X86-64 is defined as following: - Arguments are passed as for the default C calling convention - The same applies for the return value(s) - PreserveMost preserves all GPRs - except R11 - PreserveAll preserves all GPRs and all XMMs/YMMs - except R11 Reviewed by Lang and Philip llvm-svn: 199508
