[X86] Make elfiamcu an OS, not an environment. GNU tools require elfiamcu to take up the entire OS field, so, e.g. i?86-*-linux-elfiamcu is not considered a legal triple. Make us compatible.

[X86] Use correct calling convention for MCU psABI libcalls When using the MCU psABI, compiler-generated library calls should pass some parameters in-register. However, since inreg marking for x86 is currently done by the front end, it will not be applied to backend-generated calls. This is a workaround for PR3997, which describes a similar issue for -mregparm. Differential Revision: http://reviews.llvm.org/D13977 llvm-svn: 251223 2015-10-25 16:14:05 +08:00
