83b6edd760 Turn off the old way of handling debug information in the code generator. Use 
the new way, where all of the information is passed on SDNodes and machine
instructions.

47321cf01f Arrange to print constants that match "n" and "i" constraints 
in inline asm as signed (what gcc does).  Add partial support
for x86-specific "e" and "Z" constraints, with appropriate
signedness for printing.

1174b80823 fix the X86 backend to just drop llvm.declare nodes for VLAs instead of 
leaving them in the DAG and then getting selection errors.  This is a 
fix for PR3538.

abf1d4e9db Function temporaries can not overlap with retval or args.See the comment in source code to know the reason. Anything having .auto. in its name is local to a function in nature irrespective of the linkage specified. print static local variables in module level IDATA section.

9dc1507838 Turns out AnalyzeBranch can modify the mbb being analyzed. This is a nasty 
suprise to some callers, e.g. register coalescer. For now, add an parameter
that tells AnalyzeBranch whether it's safe to modify the mbb. A better
solution is out there, but I don't have time to deal with it right now.

a259483aae Get rid of the last non-DebugLoc versions of getNode! 
Many targets build placeholder nodes for special operands, e.g.
GlobalBaseReg on X86 and PPC for the PIC base.  There's no
sensible way to associate debug info with these.  I've left
them built with getNode calls with explicit DebugLoc::getUnknownLoc operands. 
I'm not too happy about this but don't see a good improvement;
I considered adding a getPseudoOperand or something, but it
seems to me that'll just make it harder to read.

1580ab6b7f Remove more non-DebugLoc getNode variants. Use 
getCALLSEQ_{END,START} to permit passing no DebugLoc
there.  UNDEF doesn't logically have DebugLoc; add
getUNDEF to encapsulate this.

66f10b55ed New feature: add support for target intrinsics being defined in the 
target directories themselves.  This also means that VMCore no longer
needs to know about every target's list of intrinsics.  Future work
will include converting the PowerPC target to this interface as an
example implementation.
