27b99c62cd add some completely unformated and probably incoherent notes about things 
I saw while reading all the commits between the 2.5 and 2.6 release branches.

412df08b59 Do away with the strange use of BitVectors in SSI, and just use normal sets. This makes the code much more C++/LLVM-ish.

18cecec6a0 SSI needs to require DT and DF transitively, since it uses them outside of its runOnFunction. 
Similarly, it can be marked setPreservesAll, since it does no work in its runOnFunction.

of the constant. This reverts r6544 and r7428.

8cebbc5761 MingW build fixes 
- MingW needs -lpsapi (in ${LIBS}) linked after -lLLVMSystem.
  Noticed by Ronald Pijnacker!

- Some parts of the System library must be build with exceptions on windows.
  Based on a patch by Jay Foad!

aa33886dd7 Fix a use-after-free in post-ra-scheduling. 
MI->addOperand invalidates references to it's operands, avoid touching
the operand after a new one was added.

532ed49e39 Expand api out in the usual inserter way, though, I do have a 
question, can we get rid of the BasicBlock versions of all inserters
and use Head == 0 to indicate the old case when GetInsertBlock == 0?

operands of instructions with these properties while breaking anti-dep.

241092d89f Add hasExtraSrcRegAllocReq and hasExtraDefRegAllocReq flags to ld / st multiple, 
ld / st pairs, etc.

8ea3f4a592 Add instruction flags: hasExtraSrcRegAllocReq and hasExtraDefRegAllocReq. When 
set, these flags indicate the instructions source / def operands have special
register allocation requirement that are not captured in their register classes.
Post-allocation passes (e.g. post-alloc scheduler) should not change their
allocations. e.g. ARM::LDRD require the two definitions to be allocated
even / odd register pair.
