Update this a bit more to represent how the prologue should work: a) frame setup instructions define the prologue b) we shouldn't change our location mid-stream Add a test to make sure that the stack adjustment stays within the prologue. llvm-svn: 165250

Debug Info: improve the verifier to check field types. Make sure the context and type fields are MDNodes. We will generate verification errors if those fields are non-empty strings. Fix testing cases to make them pass the verifier. llvm-svn: 187106

Remove the (apparently) unnecessary debug info metadata indirection. The main lists of debug info metadata attached to the compile_unit had an extra layer of metadata nodes they went through for no apparent reason. This patch removes that (& still passes just as much of the GDB 7.5 test suite). If anyone can show evidence as to why these extra metadata nodes are there I'm open to reverting this patch & documenting why they're there. llvm-svn: 174266
