recoloring cut-offs are encountered and register allocation failed.

If we ever want three or more aliases, at that point we should put MSVC
warning ids in DiagnosticGroups.td.  We can use that to support #pragma
warning.

It's better to use the same type rather than a fixed width integer type
that may be different from the return type.

This should hopefully bring the last MSVC buildbot back to green!

So that it's obvious that we pass these callbacks only to forEachUndefines.

I am not sure how to get a relocation in a .dylib, but this function would
return the wrong value if passed one.

This is consistent with -Wbuiltin-macro-redefined, and puts this common
extension warning under a flag.

This is cleaner and as efficient as before.

Seems getSomething() is more common naming scheme than just a noun
to get something, so renaming these members.

This will make it possible to implement getRelocationAddress.

Atoms with deadStripNever attribute has already been added to the
dead strip root set at end of Resolver::doDefinedAtom, so no need
to check it for each atom again.

Move code that always runs after doUndefinedAtom into doUndefinedAtom

Removes unnecessary casts from non-generic address spaces to the generic address

ELFLinkingContext has a method addUndefinedAtomsFromSharedLibrary().
The method is being used to skip a shared library within --start-group
and --end-group if it's not the first iteration of the group.

We have the same, incomplete mechanism to skip a shared library within
a group too. That's implemented in ELFFileNode. It's intended to not
return a shared library on the second or further iterations in the
first place. This mechanism is preferred over
addUndefinedAtomsFromSharedLibrary because the policy is implemented
in Input Graph -- that's what Input Graph is for.

This patch removes the dupluicate feature and fixes ELFFileNode.

When rematerializing through truncates, the coalescer may produce instructions
with dead defs, but live implicit-defs of subregs:
E.g.
  %X1<def,dead> = MOVi64imm 2, %W1<imp-def>; %X1:GPR64, %W1:GPR32

These instructions are live, and their definitions should not be rewritten.
