b92187a410 Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe what 
the variable actually tracks.

N.B., several back-ends are using "HasCalls" as being synonymous for something
that adjusts the stack. This isn't 100% correct and should be looked into.

871bb94c43 updated support for the COFF .linkonce 
Now, the .linkonce directive is emitted as part of MCSectionCOFF::PrintSwitchToSection instead of AsmPrinter::EmitLinkage since it is an attribute of the section the symbol was placed into not the symbol itself.

b4202dbb36 Fix PR7054 - Assertion `Symbol->isUndefined() && "Cannot define a symbol twice!"' failed.

detect this and emit a fatal backend error instead of aborting.
