1) don't try to optimize a sext or zext that is only used by a trunc, let
   the trunc get optimized first.  This avoids some pointless effort in
   some common cases since instcombine scans down a block in the first pass.
2) Change the cost model for zext elimination to consider an 'and' cheaper
   than a zext.  This allows us to do it more aggressively, and for the next
   patch to simplify the code quite a bit.

commonIntCastTransforms into the callers, eliminating a switch,
and allowing the static predicate  methods to be moved down to
live next to the corresponding function.  No functionality

CallExpr/ObjCMessageExpr can be visited in an "lvalue" context if it
returns a struct temporary.  Currently the analyzer doesn't reason
about struct temporary returned by function calls, but we shouldn't
crash here either.

"In order to ease automatic bindings generation, it would be helpful if boolean values were distinguishable from integers. The attached patch introduces "typedef int LLVMBool;", and uses LLVMBool instead of int throughout the C API, wherever a boolean value is called for."

the target anymore, and is used as an argument, this patch changes the
assertion.
