Devang Patel f3292b2196 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+)

Oscar Fuentes ba1186c23e 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.

NAKAMURA Takumi 4c14a5cc2c 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.

Evan Cheng 6eb516dbea 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.

Chris Lattner 3e5fbd74ed rename MVT::Flag to MVT::Glue. "Flag" is a terrible name for 
something that just glues two nodes together, even if it is
sometimes used for flags.

Wesley Peck 266f4092d7 Fix MBlaze backend call instructions so that arguments passed through registers

Daniel Dunbar 0c9d9fdd81 MC: Move target specific fixup info descriptors to TargetAsmBackend instead of

Wesley Peck 7d99b5b651 MBlaze delay slot filler was not capable of using ADDK and variants to fill delay slots. This broke several test cases when 121649 was committed. This fixes the regression.

Wesley Peck 968bc26a0a 1. Change MBlaze indirect branches to use absolute branch BRALD instead of pc relative branch BRLD. 
2. Make sure that the MBlaze stack is aligned to 4-byte boundaries.
3. Determine frame indexes that should be placed in the callers stack frame, as per the MBlaze ABI, and place them in the correct locations.
