ca70495797 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.

757e75b033 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.

1f8008cf21 fix MCSectionELF to not leak memory, just like I did for MCSymbol. 
MCSectionMachO is already fine (yay for fixed size arrays?),
MCSectionCOFF still leaks.

c28cc093e3 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.
