Ulrich Weigand 5a4c26e7bc Use the integrated assembler as default on PowerPC
This was already done in clang, this commit now uses the integrated
assembler as default when using LLVM tools directly.

A number of test cases using inline asm had to be adapted, either by
updating the expected output, or by using -no-integrated-as (for such
tests that deliberately use an invalid instruction in inline asm).
