only one of a group of possibilities.
This changes the syntax in the builtin files to represent:
, as the and operator
| as the or operator
The former syntax matches how the backend tablegen files represent
multiple subtarget features being required.
Updated the builtin and intrinsic headers accordingly for the new
syntax.

This involved removing the conditional inclusion and replacing them
with target attributes matching the original conditional inclusion
and checks. The testcase update removes the macro checks for each
file and replaces them with usage of the __target__ attribute, e.g.:
int __attribute__((__target__(("sse3")))) foo(int a) {
_mm_mwait(0, 0);
return 4;
}
This usage does require the enclosing function have the requisite
__target__ attribute for inlining and code generation - also for
any macro intrinsic uses in the enclosing function. There's no change
for existing uses of the intrinsic headers.
