802ebf9561 Fix the case when a reference to an address taken BB is emitted in one
function, then the BB is RAUW'd before the definition is emitted.  There
are still two cases not being handled, but this should improve us back to
the situation before I touched anything.

e100b5ba38 In "empty" bb, the return instruction may not be first instruction, if dbg value intrinsics are present in this bb. Use terminator to find return instructions.

b8ec72ddcb Place the LSDA into the TEXT section for x86 Darwin. If the global it's pointing
to is local to the translation unit, we need to place fill the value of that
symbol into the non-lazy pointer.

This should conclude all Darwin changes for placing the LSDA into the TEXT
section. There is some cleanup to do. I.e., there's no longer a special need for
target-specific code here. But that can come later.

b24982ba65 fix MCSectionELF to not leak memory, just like I did for MCSymbol.
MCSectionMachO is already fine (yay for fixed size arrays?),
MCSectionCOFF still leaks.

1b10191d18 fix a memory leak yjasskin pointed out: MCSymbol is bump pointer
allocated and thus not freed.  This is cool except that it contains
and std::string so the string data didn't get freed.  In any case
there is no reason to redundantly store the string data in the 
MCSymbol anyway, just make the MCSymbol ref the string data in the
MCContext StringMap.

02bf60555d eliminate some #if 0 code I added in r96905, type inference
now enforces that input/output named values have hte same type.

c008597c0a Completely rewrite tblgen's type inference mechanism,
changing the primary datastructure from being a 
"std::vector<unsigned char>" to being a new TypeSet class
that actually has (gasp) invariants!

This changes more things than I remember, but one major
innovation here is that it enforces that named input 
values agree in type with their output values.

This also eliminates code that transparently assumes (in 
some cases) that SDNodeXForm input/output types are the
same, because this is wrong in many case.

This also eliminates a bug which caused a lot of ambiguous
patterns to go undetected, where a register class would
sometimes pick the first possible type, causing an
ambiguous pattern to get arbitrary results.

With all the recent target changes, this causes no 
functionality change!
