few places in InstCombine to use it, to fix problems handling pointer
types. This fixes the recent llvm-gcc bootstrap error.

hey it uses .previous, so it should work :)

from the perspective of LLVM exception handling. Otherwise the C++ personality
function may decide not to run them, if it only detects cleanup handlers.
 - Test case for this is exceptions.m in llvm-test.

elsewhere.  Very slightly decouples DeclSpec users from knowing the exact
diagnostics to report, and makes it easier to provide different diagnostics in
some places.

When LowerSubregsInstructionPass::LowerInsert eliminates an INSERT_SUBREG
instriction because it is an identity copy, make sure that the same registers
are alive before and after the elimination.

When the super-register is marked <undef> this requires inserting an
IMPLICIT_DEF instruction to make sure the super register is live.

Fix a related bug where a kill flag on the inserted sub-register was not transferred properly.

Finally, clear the undef flag in MachineInstr::addRegisterKilled. Undef implies dead and kill implies live, so they cant both be valid.

Thanks Chris.

appropriate.  Patch per report on llvmdev.  No testcase because the 
original report didn't come with a testcase, and I can't come up with a case
that actually fails.

This will cause it to enter the ".text" section instead of "_text"
but masm is already broken.

 - The theory is these should never actually be called, since these boil down to
   passes which can access the target data via the standard mechanism.
