Benjamin Kramer f01ee30328 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!

Benjamin Kramer 3b008a3a65 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.

Mike Stump 70cb67fcf4 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?

Bob Wilson b2120755a2 Use OutStreamer.SwitchSection instead of writing out textual section directives.
Add a new TargetLoweringObjectFileMachO::getConstTextCoalSection method to
get access to that section.

Bob Wilson b633d7a665 Add a new virtual EmitStartOfAsmFile method to the AsmPrinter and use this
to emit target-specific things at the beginning of the asm output.  This
fixes a problem for PPC, where the text sections are not being kept together
as expected.  The base class doInitialization code calls DW->BeginModule()
which emits a bunch of DWARF section directives.  The PPC doInitialization
code then emits all the TEXT section directives, with the intention that they
will be kept together. But as I understand it, the Darwin assembler treats
the default TEXT section as a special case and moves it to the beginning of
the file, which means that all those DWARF sections are in the middle of
the text.  With this change, the EmitStartOfAsmFile hook is called before
the DWARF section directives are emitted, so that all the PPC text section
directives come out right at the beginning of the file.

Bob Wilson 699702e0a8 The AsmPrinter base class contains a DwarfWriter member, so there's no need
for derived AsmPrinters to add another one.  In some cases, fixing this
removes the need to override the doInitialization method.

Reid Kleckner 8ff5c19ebd Fix integer overflow in instruction scheduling. This can happen if we have
basic blocks that are so long that their size overflows a short.

Also assert that overflow does not happen in the future, as requested by Evan.

By the way, this code is buggy. You can't keep a map<MDNode *, something>
because the MDNode may be destroyed and reused for something else.

Bob Wilson 20e5f5ed79 For Darwin, emit all the text section directives together before the dwarf
section directives.  This causes the assembler to put the text sections at
the beginning of the object file, which helps work around a limitation of the
Darwin ARM relocations.  Radar 7255355.
