b0340663fe Update the LangRef documentation for llvm.ctlz and llvm.cttz to specify 
the behavior with the newly added flag for undefined results on a zero
input.

I'm terrible at documentation, so comments and suggestions welcome here.

02bdcdd326 Fix a subtle semantic issue with poison values that came up in 
recent discussions. Poison can't make every value that depends on
it act in maximally undefined ways, because the optimizer may still
hoist code following the usual rules for undef. Make Poison invoke
its full undefined behavior only when it reaches an instruction with
externally visible side effects.

db3a5dbdb5 Rename "Trap Values" to "Poison Values", to better reflect their 
purpose, and to avoid ambiguity with other uses of the word "trap"
in LangRef.

54ca22353a Mention that -O4 does result in more optimization when used with 
-fplugin-arg-dragonegg-enable-gcc-optzns, though it usually isn't
a win.

6bf1babd92 Add a link from the LLVM release notes to the Clang release notes. 
I suspect we could profitably remove/move some of the bullet points
under Clang here to the Clang notes in order to keep things clean on
both sides. Unless I hear objections I'll start doing that once folks
have read over the Clang notes a bit.
