to initializer expressions in an array allocated using ASTContext.

This plugs a memory leak when ASTContext uses a BumpPtrAllocator to
allocate memory for AST nodes.

In my mind this isn't an ideal solution; it would be nice to have
a general "vector"-like class that allocates memory using ASTContext,
but whose guts could be separated from the methods of InitListExpr
itself.  I haven't gone and taken this approach yet because it isn't
clear yet if we'll eventually want an alternate solution for recylcing
memory using by InitListExprs as we are constructing the ASTs.

Moderate the weight given to very small intervals.

The spill weight given to new intervals created when spilling was not
normalized in the same way as the original spill weights calculated by
CalcSpillWeights. That meant that restored registers would tend to hang around
because they had a much higher spill weight that unspilled registers.

This improves the runtime of a few tests by up to 10%, and there are no
significant regressions.
