Add strict versions of insertWith and insertWithKey to IntMap

[tibbe]

A strict version of insertWith is needed when the value stored in the IntMap is e.g. an Int or some other value that's more efficiently stored in WHNF.

'merge' is the wrong state for this; please use 'patch'.

Was this proposal discussed on the mailing list? Can you add a link to the proposal thread please?

insertWithKey' calls insertWithKey; is that really right?

Here's the libraries email:  http://permalink.gmane.org/gmane.comp.lang.haskell.libraries/13489

insertWithKey' should call insertWithKey' in the recursive call! Could you fix that when applying or should I add a new patch?

Corrected version of strict-insert-with.dpatch

[tibbe]

I've attached a fixed version of the patch that applies cleanly to the current HEAD. Please apply.

Applied, and I took the liberty of making a few tweaks:

  * Tweak insertWith' and insertWithKey' to better match the non-' versions
  They now are not marked inlinable, force the key, and are exported.
