9be547cfd3 Add a possibility to switch between CFI directives- and table-based frame description emission. Currently all the backends use table-based stuff.

95f6ebcb37 Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe what 
the variable actually tracks.

N.B., several back-ends are using "HasCalls" as being synonymous for something
that adjusts the stack. This isn't 100% correct and should be looked into.

TimePassesIsEnabled. This should allow make check to pass.

ee2fbbc978 change the LabelSDNode to be EHLabelSDNode and make it hold 
an MCSymbol.  Make the EH_LABEL MachineInstr hold its label
with an MCSymbol instead of ID.  Fix a bug in MMI.cpp which
would return labels named "Label4" instead of "label4".

34adc8d225 change EH related stuff (other than EH_LABEL) to use MCSymbol 
instead of label ID's.  This cleans up and regularizes a bunch 
of code and makes way for future progress.

Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
is largely copy and paste from DwarfException/MachineModuleInfo
and other places.  This is very sad and disturbing. :(

One major change here is that TidyLandingPads moved from being
called in DwarfException::BeginFunction to being called in
DwarfException::EndFunction.  There should not be any 
functionality change from doing this, but I'm not an EH expert.

41e275dc8e simplify EmitFrameMoves to take BaseLabel in as a symbol 
instead of as a stem+idx pair, simplify the "is a new 
location" check to use symbol comparison.

71c30c164f move three lowering hooks from MAI to TLOF and make one of them 
semantic instead of syntactic.  This completes MCization of
darwin/x86[-64]!

for darwin/x86 to be completely mcized.

7e998b7363 add some fixme's for MCizing. EH still has a few things that 
need to be MCized, but the last debug info thing are LEB and
cygwin specific (which the MC api doesn't support yet) and
one specific form of EmitReference which I'll tackle next.

566cae9086 eliminate EOL, adding all comments with the OutStreamer.AddComment 
method.  With this, comments should end up on the same lines as the .byte
directives (for example) and we now get no output with:

$ llc CodeGen/X86/2009-02-12-DebugInfoVLA.ll -o - -filetype=null -asm-verbose

woot.

4d728127fb now that the debug and eh emitters use a common .set counter, 
we can eliminate "flavor".

27a9732450 simplify EmitSectionOffset to always use .set if it is 
available, the only thing this affects is that we produce
.set in one case we didn't before, which shouldn't harm
anything.  Make EmitSectionOffset call EmitDifference
instead of duplicating it.

c3a9376215 A much cleaner (and less code!) way of inserting the correct amount of padding 
for alignment into the LSDA. If the TType base offset is emitted, then put the
padding there. Otherwise, put it in the call site table length. There will be no
conflict between the two sites when placing the padding in one place.

6394521a2b Add another (and hopefully the last) exception case, where once we recalculate 
the alignment requirement, if it no longer makes the TType base offset overflow
into extra bytes, then we need to pad to those bytes ourselves.
