a5c177e70a We need to pass the TargetMachine object to the InstPrinter if we are printing 
the alias of an InstAlias instead of the thing being aliased. Because we need to
know the features that are valid for an InstAlias.

This is part of a work-in-progress.

68e6beeccc Revert r124611 - "Keep track of incoming argument's location while emitting LiveIns." 
In other words, do not keep track of argument's location.  The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body.
This requires some coordination with debugger to get this working. 
 - The debugger needs to be aware of prolog_end attribute attached with line table entries.
 - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+)

00d78f1348 Use explicit add_subdirectory's for LLVM target sublibraries instead 
of testing for its presence at cmake time.

This way the build automatically regenerates the makefiles when a svn
update brings in a new sublibrary.

6904f05e60 Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 generally. 
No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32. In llvm side, i686 and x64 can be treated as similar way.

c36b7069b4 Do not model all INLINEASM instructions as having unmodelled side effects. 
Instead encode llvm IR level property "HasSideEffects" in an operand (shared
with IsAlignStack). Added MachineInstrs::hasUnmodeledSideEffects() to check
the operand when the instruction is an INLINEASM.

This allows memory instructions to be moved around INLINEASM instructions.
