Add a new method GetFunctionAddressAndSizeVector to DWARFCallFrameInfo.
This returns a vector of <file address, size> entries for all of
the functions in the module that have an eh_frame FDE.
Update ObjectFileMachO to use the eh_frame FDE function addresses if
the LC_FUNCTION_STARTS section is missing, to fill in the start
addresses of any symbols that have been stripped from the binary.
Generally speaking, lldb works best if it knows the actual start
address of every function in a module - it's especially important
for unwinding, where lldb inspects the instructions in the prologue
of the function. In a stripped binary, it is deprived of this
information and it reduces the quality of our unwinds and saved
register retrieval.
Other ObjectFile users may want to use the function addresses from
DWARFCallFrameInfo to fill in any stripped symbols like ObjectFileMachO
does already.

Remove dependence on canonical induction variable
When using the scev based code generation, we now do not rely on the presence
of a canonical induction variable any more. This commit prepares the path to
(conditionally) disable the induction variable canonicalization pass.

Exploit this-return of a callsite in a this-return function.
For constructors/desctructors that return 'this', if there exists a callsite
that returns 'this' and is immediately before the return instruction, make
sure we are using the return value from the callsite.
We don't need to keep 'this' alive through the callsite. It also enables
optimizations in the backend, such as tail call optimization.

This reverts commit

The code is obviously wrong, but the trivial fix causes
inefficient code generation on X86. Somebody with more
knowledge of the code needs to take a look here.

Do not consider comments when adjusting to local indent style.
Before (when only reformatting "int b"):
int a; // comment
// comment
int b;
After:
