74b96ac7b8 The DIBuilder class is just a wrapper around debug info creation 
(a.k.a. MDNodes). The module doesn't belong in Analysis. Move it to the VMCore
instead.

e8949ecfa6 Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp and 
include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h.

The reasoning is because the DebugInfo module is simply an interface to the
debug info MDNodes and has nothing to do with analysis.

be0b8939c0 Switch all register list clients to the new MC*Iterator interface. 
No functional change intended.

Sorry for the churn. The iterator classes are supposed to help avoid
giant commits like this one in the future. The TableGen-produced
register lists are getting quite large, and it may be necessary to
change the table representation.

This makes it possible to do so without changing all clients (again).

39493f0f97 Revert "Reorder the sections being output to reduce the number of assembler" 
The inline table needs to be constructed ahead of time so that it doesn't try to
create new strings while we're emitting everything.

7d0d3c2d58 Move global variables in TargetMachine into new TargetOptions class. As an API 
change, now you need a TargetOptions object to create a TargetMachine. Clang
patch to follow.

One small functionality change in PTX. PTX had commented out the machine
verifier parts in their copy of printAndVerify. That now calls the version in
LLVMTargetMachine. Users of PTX who need verification disabled should rely on
not passing the command-line flag to enable it.

5f6b14719f The dwarf standard says that the only differences between a out-of-line 
instance and a concrete inlined instance are the use of DW_TAG_subprogram
instead of DW_TAG_inlined_subroutine and the who owns the tree.

We were also omitting DW_AT_inline from the abstract roots. To fix this,
make sure we mark abstract instance roots with DW_AT_inline even when
we have only out-of-line instances referring to them with DW_AT_abstract_origin.

FileCheck is not a very good tool for tests like this, maybe we should add
a -verify mode to llvm-dwarfdump.
