Windows: Use GetModuleHandleEx instead of LoadLibrary

We were using an anti-pattern of:
 - LoadLibrary
 - GetProcAddress
 - FreeLibrary

This is problematic because of several reasons:
 - We are holding on to pointers into a library we just unloaded.
 - Calling LoadLibrary results in an increase in the reference count of
   the library in question and any libraries that it depends on and
   so-on and so-forth.  This is none too quick.

Instead, use GetModuleHandleEx with GET_MODULE_HANDLE_EX_FLAG_PIN.  This
is done because because we didn't bring the reference for the library
into existence and therefor shouldn't count on it being around later.

but confused the verifier since now the s3 load had Q0<imp-use> with
no definition above it.

This should mark such uses <undef> as well. The liveness structure at
the beginning and end of the block is unaffected, and the true sN
definitions should prevent any dodgy reorderings being introduced

Fix a bug in Dead Argument Elimination.

  If a function seen at compile time is not necessarily the one linked to
the binary being built, it is illegal to change the actual arguments
passing to it.

  e.g.
   --------------------------
   void foo(int lol) {
     // foo() has linkage satisifying isWeakForLinker()
     // "lol" is not used at all.
   }

   void bar(int lo2) {
      // xform to foo(undef) is illegal, as compiler dose not know which
      // instance of foo() will be linked to the the binary being built.
      foo(lol2);
   }
  -----------------------------

  Such functions can be captured by isWeakForLinker(). NOTE that
mayBeOverridden() is insufficient for this purpose as it dosen't include
linkage types like AvailableExternallyLinkage and LinkOnceODRLinkage.
Take link_odr* as an example, it indicates a set of *EQUIVALENT* globals
that can be merged at link-time. However, the semantic of
*EQUIVALENT*-functions includes parameters. Changing parameters breaks
the assumption.

  Thank John McCall for help, especially for the explanation of subtle
difference between linkage types.
