d5c4589795 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+)

59c8ae34f7 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.

cec3b226a4 move all the target's asmprinters into the main target. The piece 
that should be split out is the InstPrinter (if a target is mc'ized).
This change makes all the targets be consistent.

f6e5e02c9b Inside the calling convention logic LocVT is always a simple 
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.

55043ef46a fix a long standing wart: all the ComplexPattern's were being 
passed the root of the match, even though only a few patterns
actually needed this (one in X86, several in ARM [which should
be refactored anyway], and some in CellSPU that I don't feel 
like detangling).   Instead of requiring all ComplexPatterns to
take the dead root, have targets opt into getting the root by
putting SDNPWantRoot on the ComplexPattern.

74db02758b Don't call Predicate_* methods directly from Sparc target.

The Predicate_* methods are not used by TableGen any longer. They are only
emitted for the sake of legacy code.

7af3eff94d RISC architectures get their memory operand folding for free. 
The only folding these load/store architectures can do is converting COPY into a
load or store, and the target independent part of foldMemoryOperand already
knows how to do that.
