* In preparation of compiling our kernels with -ffreestanding, explicitly mapkettenis2017-01-241-1/+4
| | | | | | | | | a few performance-critical functions to compiler builtins. Since the builtins supported by gcc3, gcc4 and clang are not the same, there are (unfortunately) some compiler checks to make sure we only do the mapping for builtins that are actually supported by the compiler. ok jca@, tom@, guenther@

| | | | | | | | | | | | | type characteristics. internal_types.h will contain only settings invisible from standard C, e.g., in the __* or _[A-Z]* namespace, and be reused by files like limits.h. This allows us to shorten machine/limits.h greatly, as all the common defines are now in sys/limits.h, plus a small stub in internal_types.h. Tested on all arches as far as I know. Approved after discussion with art, millert, deraadt, and others.
