getFunctionAlignment and the corresponding use of that value in the ARM
asm printer, but now we're using the standard asm printer. The result of
this was that function alignments were dropped completely for Thumb functions.

Objective-C metadata types which should be marked as "weak", but which the
linker will remove upon final linkage. However, this linkage isn't specific to
Objective-C.
For example, the "objc_msgSend_fixup_alloc" symbol is defined like this:
.globl l_objc_msgSend_fixup_alloc
.weak_definition l_objc_msgSend_fixup_alloc
.section __DATA, __objc_msgrefs, coalesced
.align 3
l_objc_msgSend_fixup_alloc:
.quad _objc_msgSend_fixup
.quad L_OBJC_METH_VAR_NAME_1
This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".
Currently only supported on Darwin platforms.

to update their code to high-level interfaces
If you get compile errors in your project
please update your code according to the
comments.
This is a re-commit of r107396 which causes
compile errors for the indicated usage patterns
instead of link errors (which are less easy to
fix because of missing source location).
If you get compile errors please perform
following functionally equivalent transformations:
- getOperand(0) ---> getCalledValue()
- setOperand(0, V) ---> setCalledFunction(V)
This will make your code more future-proof
and avoid potentially hard-to-debug bugs.

such a way that debug info for symbols preserved even if symbols are
optimized away by the optimizer.
Add new special pass to remove debug info for such symbols.

number of instructions in common testcases by 4%.

- Add encode bits for VEX_W
- All 128-bit SSE 1 & SSE2 instructions that are described
in the .td file now have a AVX encoded form already working.

selectors in the program again.

entries associated with the value being erased in the
folding set map. These entries used to be harmless, because
a SCEVUnknown doesn't store any information about its Value*,
so having a new Value allocated at the old Value's address
wasn't a problem. But now that ScalarEvolution is storing more
information about values, this is no longer safe.

LocalRewriter::runOnMachineFunction uses this information to mark dead spill
slots.
This means that InlineSpiller now also works for functions that spill.
