d3f41e8939 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.

0344874921 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.

679708ee34 Correctly determine if the @property has been previously declared. If 
a property has the same name as the ivar it wraps then the old logic
wouldn't find the previous property declaration.

ea16606fcd During C++ name lookup, use DeclContext::Equals() rather than 
comparing DeclContext pointers, to avoid having to remember to call
getPrimaryContext() everywhere. This is the last part PR6594.

6623006249 Implement C++ [temp.local]p8, which specifies that a template 
parameter hides a namespace-scope declararion with the same name in an
out-of-line definition of a template. The lookup requires a strange
interleaving of lexical and semantic scopes (go C++), which I have not
yet handled in the typo correction/code completion path.

Fixes PR6594.

3e11ebebc8 Remember declaration scope qualifiers in the AST. Imposes no memory overhead 
on unqualified declarations.

Patch by Enea Zaffanella!  Minimal adjustments:  allocate the ExtInfo nodes
with the ASTContext and delete them during Destroy().  I audited a bunch of
Destroy methods at the same time, to ensure that the correct teardown was
being done.

632eb65cd2 fix MCSectionELF to not leak memory, just like I did for MCSymbol. 
MCSectionMachO is already fine (yay for fixed size arrays?),
MCSectionCOFF still leaks.

133487696a 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.

cabe037b2d 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!
