Enable debug for MSP430

Hi Gents,

For those of us with out-of-tree backends which are not 32bit, the msp430 backend is a useful vehicle for examining changes and testing out ideas.

So I was wondering about enabling debug output on the MSP430 backend so that I can illustrate a few issues to Adrian and you on the variable pieces side. (there doesn't appear to be any specific person claiming the msp430 code right now).

I have a question tho.

the following patch :

diff --git a/llvm/lib/Target/MSP430/MCTargetDesc/MSP430MCAsmInfo.cpp b/llvm/lib/Target/MSP430/MCTargetDesc/MSP430MCAsmInfo.cpp
index df1aa1a..844db93 100644
--- a/llvm/lib/Target/MSP430/MCTargetDesc/MSP430MCAsmInfo.cpp
+++ b/llvm/lib/Target/MSP430/MCTargetDesc/MSP430MCAsmInfo.cpp
@@ -24,4 +24,6 @@ MSP430MCAsmInfo::MSP430MCAsmInfo(StringRef TT) {

   AlignmentIsInBytes = false;
   UsesELFSectionDirectiveForBSS = true;

I think that is the case. ExceptionsType is probably just a bad name
for the frame unwind format.

Cheers,
Rafael

Yes. This is the case.
