New Revision: 95623

URL: http://llvm.org/viewvc/llvm-project?rev=95623&view=rev
Log:
Pass inline keyword to optimizer as the new InlineHint function attribute.

At the moment the inlinehint attribute is ignored by the Inliner unless you
pass a -respect-inlinehint option.  This will soon be the default.

The inlinehint attribute is set if the inline keyword is explicitly specified
on any declaration.
