Reid Spencer 19dc32a2d4 Add some things needed by the llvm-gcc version supporting bit accurate integer ... types: 1. Functions to compute div/rem at the same time. 2. Further assurance that an APInt with 0 bitwidth cannot be constructed. 3. Left and right rotate operations. 4. An exactLogBase2 function which requires an exact power of two or it returns -1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37025 91177308-0d34-0410-b5e6-96231b3b80d8		2007-05-13 23:44:59 +00:00
