this now avoids a O(n)  temporary std::strings where N is the length of 
the string after -L.

we pushed the beginning of the interval back 1, so the
interval would overlap with inputs that die.  We were
also pushing the end of the interval back 1, though,
which means the earlyclobber didn't overlap with other
output operands.  Don't do this.  PR 4964.

Ok, an AssertingVH definitely doesn't work for now because we free our cache after the optimizer may have hacked on the module. Use a WeakVH instead.

It prints the content of all bbs, instead of printing empty bbs to make the
CFG more readable.  Fix this.  Patch by Tobias Grosser.

Fix PR4926. When target hook EmitInstrWithCustomInserter() insert new basic blocks and update CFG, it should also inform sdisel of the changes so the phi source operands will come from the right basic blocks.

"->", or "::" if we will be looking into a dependent context. It's not
wrong to use the "template" keyword, but it's to needed, either.

template smarter, by taking into account which function template
parameters are deducible from the call arguments. For example,

  template<typename RandomAccessIterator>
  void sort(RandomAccessIterator first, RandomAccessIterator last);

will have a code-completion string like

  sort({RandomAccessIterator first}, {RandomAccessIterator last})

since the template argument for its template parameter is
deducible. On the other hand,

  template<class X, class Y>
  X* dyn_cast(Y *Val);

will have a code-completion string like

  dyn_cast<{class X}>({Y *Val})

since the template type parameter X is not deducible from the function
call.
