Dan Gohman 33a3fd0b9c Revert the addition of hasNoPointerOverflow to GEPOperator. 
Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.

Remove a few optimizations that depended on this flag.

Bill Wendling a3c6f6bffa Add plumbing for the `linker_private' linkage type. This type is meant for 
"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.

Eli Friedman be853b7b5d Don't override LowerArguments in the SPARC backend. In addition to 
being more consistent with other backends, this makes the SPARC backend 
deal with functions with arguments with illegal types correctly, which 
fixes some tests in test/CodeGen/Generic.

Jakob Stoklund Olesen aba695c7d0 Fix http://llvm.org/bugs/show_bug.cgi?id=4583 
Inline asm instructions may have additional <imp-def,kill> register operands.
These operands are not marked with a flag like the normal asm operands, so we
must not assert that there is a flag.

Daniel Dunbar c3ab4c6c98 Detect when the current generation point is unreachable after emitting 
expressions.
 - This generally catches the important case of noreturn functions.

 - With the last two changes, we are down to 152 unreachable blocks emitted on
   403.gcc, vs the 1805 we started with.

Daniel Dunbar b6adc43f6e Avoid generation of dead code in a few more situations. 
- Emit variable declarations as "simple", we want to avoid forcing the creation
   of a dummy basic block, but still need to make the variable available for
   later use.

 - With that, we can now skip IRgen for other unreachable statements (which
   don't define a label).

 - Anders, I added two fixmes on calls to EmitVLASize, can you check them?
