Consider this function:

void foo() { __builtin_unreachable(); }

_func1:
Leh_func_begin0:
pushq %rbp
Ltmp0:
movq %rsp, %rbp
Ltmp1:
Leh_func_end0:
This prolog adds a new Call Frame Information (CFI) row to the FDE with an
address that is not within the address range of the code it describes -- part is
equal to the end of the function -- and therefore results in an invalid EH
frame. If we emit a nop in this situation, then the CFI row is now within the
address range.

Revert r108369, sorting llvm.dbg.declare information by source position,
...
since it doesn't work for front-ends which don't emit column information
(which includes llvm-gcc in its present configuration), and doesn't
work for clang for K&R style variables where the variables are declared
in a different order from the parameter list.
Instead, make a separate pass through the instructions to collect the
llvm.dbg.declare instructions in order. This ensures that the debug
information for variables is emitted in this order.

Allow x87 FP registers to be alive globally in a function.
...
FP_REG_KILL instructions are still inserted, but can be disabled by passing
-live-x87 to llc. The X87FPRegKillInserterPass is going to be removed shortly.
CFG edges are partioned into bundles where the x87 stack must be allocated
identically. Code is insertad at the end of each basic block that shuffles the
live FP registers to match the outgoing bundles expectations.
This fix is in preparation for some upcoming register allocator improvements
that may extend the live range of registers beyond a basic block, similar to
LICM. It also provides a nice runtime speedup if you are building with
-mfpmath=387.
