Break the arc-profile code out to a function like the notes emission code is,

The only functionality change is that we no longer modify the Module when the
Module has no debug info to use.

Introduce Rewriter::IncreaseIndentation() which increase indentations for the lines between the given source range.
To determine what the indentation should be, a SourceLocation 'parentIndent' parameter is used that should be at
a source location with an indentation one degree lower than the given range.

Add support for "dynamic values" for C++ classes.  This currently only works for "frame var" and for the
expressions that are simple enough to get passed to the "frame var" underpinnings.  The parser code will
have to be changed to also query for the dynamic types & offsets as it is looking up variables.

The behavior of "frame var" is controlled in two ways.  You can pass "-d {true/false} to the frame var
command to get the dynamic or static value of the variables you are printing.

There's also a general setting:

target.prefer-dynamic-value (boolean) = 'true'

which is consulted if you call "frame var" without supplying a value for the -d option.

Objective-C pointer to void* as a "conversion to void*". This allows
us to prefer an Objective-C object pointer conversion to a superclass
object pointer over an Objective-C object pointer conversion to
cv-void*. Fixes PR9735.

DWARFDebugAranges::Sort() calls std::stable_sort() over a set of address ranges
and then proceeds to collapse neighboring ranges together.

One problem with the current implementation is that it does an incomplete job.
When a pair of ranges are merged the next pair considered does not include the
just-merged range.  IOW, three consecutive ranges are never collapsed into one.

Another problem is that for each range merged we are calling
std::vector::erase() which "shifts" all remaining elements of the vector by one
position on every merge.  The end result (in the worst case) is a quadratic
algorithm -- not good when the input vector is large.

The following patch merges all consecutive ranges and removes the quadratic
behavior.  The implementation uses an auxiliary vector of indices in order to
remember all ranges that can be dropped, then performs the coalescing of ranges
in a single pass.

Patch from Stephen Wilson with some minor modification by me.

address space. I could see that this functionality would be useful,
but not in its current form (where the address space is ignored):
rather, we'd want to encode the address space into the parameter list
passed to operator new/operator delete somehow, which would require a
bunch more semantic analysis.
