37925d3f39 Integrate exception filter support and exception catch support. This 
simplifies the code in DwarfWriter, allows for multiple filters and
makes it trivial to specify filters accompanied by cleanups or catch-all
specifications (see next patch).  What a deal!  Patch blessed by Anton.

0f184e86ab Mark all calls as "could throw", when exceptions are enabled. Emit necessary LP info too. This fixes PR1439

it occurs for multiple landing pads.

ad0dd14386 Emit function debug frames in one atom. This will prevent us from generating incorrect assembler in case of both 
debug information & exception information presented.

100919126f Emit multiple common EH frames for multiple (including blank) personality 
functions. This partly fixes PR1414: now we're restricted only to one
personality function per eh frame, not per module. Further work on
"multiple personalities" topic needs representative example.

7daaf71b29 More DWARF-related things cleanup: 
1. Fix PR1380
2. Apply Duncan's patch from PR1410
3. Insert workaround for "one personality function per module" as noted in PR1414
4. Emit correct debug frames for x86/linux. This partly fixes DebugInfo/2006-11-06-StackTrace.cpp: stack trace is
shown correctly, but arguments for function on top of stack are displayed incorrectly.

7f6a73eb5c Added an automatic cast to "std::ostream*" etc. from OStream. We then can 
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.
