Add test case for testing InstCombine with arbitrary precision integer types. These tests mimic the integer test cases in the normal InstCombine test suite but use "strange" integer bit widths. Most tests written by Zhou Sheng, a few by me. llvm-svn: 35284 2007-03-23 21:48:34 +01:00			`; Tests to make sure elimination of casts is working correctly`

Convert the rest of the InstCombine tests from notcast to FileCheck. llvm-svn: 83828 2009-10-12 09:18:14 +02:00			`; RUN: opt < %s -instcombine -S \| FileCheck %s`
