Do not held on to DenseMap slot accross map insertion. The insertion may cause the map to grow rending the slot invalid.
Use this opportunity to use ValueMap instead of DenseMap.

If there is not any llvm instruction associated with each lexical scope encoded in debug info then create such scope on demand for variable info.

Extract scope information from the variable itself, instead of relying on alloca or llvm.dbg.declare location.

While recording beginning of a function, use scope info from the first location entry instead of just relying on first location entry itself.

Check invalid debug info for enums. This may happen when underlyng enum is optimized away. Eventually DwarfChecker will clean this up during llvm verification stage.

Do not record line number to implicitly mark start of function if function has arguments. Extra line number entries trip gdb in some cases.

Existence of a compile unit for input source file is a good indicator to check debug info's presence in a module.

This can happen if debug info is processed lazily.

Here, foo's DIE is parent of bar's DIE.

information.  This allows arbitrary code involving DW_OP_plus_uconst
and DW_OP_deref.  The scheme allows for easy extention to include,
any, or all of the DW_OP_ opcodes.  I thought about just exposing all
of them, but, wasn't sure if people wanted the dwarf opcodes exposed
in the api.  Is that a layering violation?

With this scheme, the entire existing block scheme used by llvm-gcc
can be switched over to the new scheme.  I think that would be
cleaner, as then the compiler specific bits are not present in llvm
proper.  Before the old code can be yanked however, similar code in
clang would have to be removed.

Next up, more testing.

the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.
