AMDGPU/SI: Add implicit register operands in the correct order.
This commit fixes a bug in the class 'SIInstrInfo' where the implicit register
machine operands were added to a machine instruction in an incorrect order -
the implicit uses were added before the implicit defs.
I found this bug while working on moving the implicit register operand
verification code from the MIR parser to the machine verifier.
This commit also makes the method 'addImplicitDefUseOperands' in the machine
instruction class public so that it can be reused in the 'SIInstrInfo' class.

Start cleanup of unique_ptr tests.
One of the last sections of tests that still fail in C++03 are the unique_ptr
tests. This patch begins cleaning up the tests and fixing C++03 failures.
The main changes of this patch:
- The "Deleter" type in "deleter.h" tried to be "move-only" in C++03. However
the move simulation no longer works (see "__rv"). "Deleter" is now copy
constructible in C++03. However copying "Deleter" will "move" the test value
instead of copying it.
- Reduce the unique.ptr.single.ctor tests files from ~25 to 4. There is no
reason the tests were split through so many files.

TableGen: Support folding casts from bits to int
This is to fix an incorrect error when trying to initialize
DwarfNumbers with a !cast<int> of a bits initializer.
getValuesAsListOfInts("DwarfNumbers") would not see an IntInit

It seems likely that this could be generalized to attempt
the convertInitializerTo for any type. I'm not really sure
why the existing code seems to special case the string cast cases
when convertInitializerTo seems like it should generally handle this
sort of thing.

fix memcpy/memset/memmove lowering when optimizing for size
Fixing MinSize attribute handling was discussed in D11363.
This is a prerequisite patch to doing that.
The handling of OptSize when lowering mem* functions was broken
on Darwin because it wants to ignore -Os for these cases, but the
existing logic also made it ignore -Oz (MinSize).
The Linux change demonstrates a widespread problem. The backend
doesn't usually recognize the MinSize attribute by itself; it
assumes that if the MinSize attribute exists, then the OptSize
attribute must also exist.
Fixing this more generally will be a follow-on patch or two.
