930ca98433 Fix pr19645.
The fix itself is fairly simple: move getAccessVariant to MCValue so that we
replace the old weak expression evaluation with the far more general
EvaluateAsRelocatable.

This then requires that EvaluateAsRelocatable stop when it finds a non
trivial reference kind. And that in turn requires the ELF writer to look
harder for weak references.

Last but not least, this found a case where we were being bug by bug
compatible with gas and accepting an invalid input. I reported pr19647
to track it.

4266ae8067 [C++11] More 'nullptr' conversion or in some cases just using a boolean check instead of comparing to nullptr.

8a272f00a0 MC: add a RefKind field to MCValue
This is principally to allow neater mapping of fixups to relocations
in ARM64 ELF. Without this, there isn't enough information available
to GetRelocType, leading to many more fixup_arm64_... enumerators.

9a1d20042f MCValue: Change to holding MCSymbolRefExprs instead of MCSymbols, we will need this for accessing to symbol modifiers.

10b318bcb3 now that MCSymbol::print doesn't use it's MAI argument, we can
remove it and change all the code that prints MCSymbols to use 
<< instead, which is much simpler and cleaner.

684c593d05 Thread an MCAsmInfo pointer through the various MC printing APIs,
and fix a few things using << on MCSymbols to use ->print(). No
functionality change other than unbreaking my previous patch.
