Chris Lattner 53af2d13e7 reenable the piece that turns trunc(zext(x)) -> x even if zext has multiple uses, ...

codegen has no apparent problem with the trunc version of this, because it turns
into a simple subreg idiom

ExecutionEngine

"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."

Linker

Fixed linking of modules containing aliases to constant bitcasts. Existing behaviour first tried to replace the aliases with the global that they aliased (rather than the bitcast), causing a crash on an assert because the types didn't match. When this was fixed, it then did the same thing creating the new alias (creating an alias with a different type to its aliasee).
