Add support for a missed case when the symbols in a difference
expression are in the same section but not the same fragment.

Add support for the R_ARM_TARGET1 relocation, which should be given to relocations applied to all C++ constructors and destructors.

This enables the linker to match concrete relocation types (absolute or relative) with whatever library or C++ support code is being linked against.

of several newly un-defaulted switches. This also helps optimizers
(including LLVM's) recognize that every case is covered, and we should
assume as much.

VK_PPC_{HA,LO}16 into darwin and gas variants.

Darwin wants {ha,lo}16(symbol) while gnu as wants symbol@{ha,l}.

Add support for Thumb interworking addresses for symbol offsets that get constant folded very early.

in the right direction. It eliminated some hacks and will unblock codegen
work. But it's far from being done. It doesn't reject illegal expressions,
e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.

IsSymbolRefDifferenceFullyResolved(). For example, we will now fold away
something like:
