If there's more than one function operand to a call instruction, be conservative

and don't assume that the call doesn't throw. It would be nice if there were a

architecture we care about normally only have one operand for a call instruction
(x86 and arm).

Fix DenseMap iterator constness.
...
This patch forbids implicit conversion of DenseMap::const_iterator to
DenseMap::iterator which was possible because DenseMapIterator inherited
(publicly) from DenseMapConstIterator. Conversion the other way around is now
allowed as one may expect.
The template DenseMapConstIterator is removed and the template parameter
IsConst which specifies whether the iterator is constant is added to
DenseMapIterator.
Actually IsConst parameter is not necessary since the constness can be
determined from KeyT but this is not relevant to the fix and can be addressed
later.
