When producing objects that are abi compliant we are 
marking neither the object file nor the assembly file
correctly and thus generate warnings. 

We need to set the EF_CPIC flag in the ELF header when
generating direct object.

Note that the warning is only generated when compiling without PIC.

When compiling with clang the warning will be suppressed by supplying:

 -Wa,-mno-shared -Wa,-call_nonpic

Also the following directive should also be added:

	.option	pic0

when compiling without PIC,  This eliminates the need for supplying:

  -mno-shared -call_nonpic

on the assembler command line.

For decoding, keep the current behavior of always decoding these as their REP
versions. In the future, this could be improved to recognize the cases where
these behave as XACQUIRE and XRELEASE and decode them as such.

CodeGen: Have 'this'-returning constructors and destructors to take advantage of the new backend 'returned' attribute.

The backend will now use the generic 'returned' attribute to form tail calls where possible, as well as avoid save-restores of 'this' in some cases (specifically the cases that matter for the ARM C++ ABI).

This patch also reverts a prior front-end only partial implementation of these optimizations, since it's no longer required.

Transforms will now make changes to headers if header modifications have been
enabled.

FIXME: Only UseNullptr contains a cursory header modification test. Other
transforms should have them too.

To make it possible for replacements made to headers as part of transforming
one translation unit to not be visible to the transform of other translation
units, Transform now handles replacement application as part of its
end-of-source handling. Several things were simplified as a result:

- The duplicated code in every transform for applying replacements is now gone
  and replaced with one location in Transform.
- RefactoringTool is no longer used since Transform houses the Replacements
  structure.
- RewriterContainer is now a private implementation detail of Transform (also
  renamed to RewriterManager since its behaviour is slightly different now with
  respect to lifetime of objects).
- There's now no distinction between input and output file state.

Misc notes:

- Interface changes reflected in unit tests.
- Replacements for files other than the main file are assumed to be for headers
  and stored as such.

The CMake build was still using it because I forgot to s/CLANG/LLVM/ in

When using a positive offset, literal loads where encoded
as if it was negative, because:
- The sign bit was not assigned to an operand
- The addrmode_imm12 operand was not encoding the sign bit correctly

This patch also makes the assembler look at the .w/.n specifier for
loads.
