017d121c59 Do not hold on to a map slot while new entries may be inserted into the map. 
Use ValueMap, instead of std::map.

01c69374b5 The "ReadOnlyWithRel" enum seems to apply more to what Darwin does with the EH 
exception table than DataRel.

ac18929801 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
way to determine which is the callee and which is a parameter. In practice, the
architecture we care about normally only have one operand for a call instruction
(x86 and arm).

81cf432569 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.

Patch by Victor Zverovich!
