* Reintroduce the InlineHint function attribute.Jakob Stoklund Olesen2010-02-061-0/+1
| | | | | | | | | | | | This time it's for real! I am going to hook this up in the frontends as well. The inliner has some experimental heuristics for dealing with the inline hint. When given a -respect-inlinehint option, functions marked with the inline keyword are given a threshold just above the default for -O3. We need some experiments to determine if that is the right thing to do. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95466 91177308-0d34-0410-b5e6-96231b3b80d8

Also added versions of the move string and store string instructions without the repeat prefixes to X86InstrInfo.td.
