- Also adds a new POPCNT subtarget feature that is currently enabled if the target
supports SSE4.2 (nehalem) or SSE4A (barcelona).

Lifted adjustFixupValue() from Darwin for sharing w ELF.
Test added
TODO:
refactor ELFObjectWriter::RecordRelocation more.
Possibly share more code with Darwin?
Lots more relocations...

legalization time. Since at legalization time there is no mapping from
SDNode back to the corresponding LLVM instruction and the return
SDNode is target specific, this requires a target hook to check for
eligibility. Only x86 and ARM support this form of sibcall optimization
right now.

We need to check if the individual vector elements are sign/zero-extended
values. For now this only handles constants values. Radar 8687140.

state. Previously Thumb2 would restore sp from fp like this:
mov sp, r7
sub, sp, #4
If an interrupt is taken after the 'mov' but before the 'sub', callee-saved
registers might be clobbered by the interrupt handler. Instead, try
restoring directly from sp:
add sp, #4
Or, if necessary (with VLA, etc.) use a scratch register to compute sp and
then restore it:
sub.w r4, r7, #8
mov sp, r7

DAGCombine from making an illegal transformation of bitcast of a scalar to a
vector into a scalar_to_vector.

if the extension types were not the same. The result was that if you
fed a select with sext and zext loads, as in the testcase, then it
would get turned into a zext (or sext) of the select, which is wrong
in the cases when it should have been an sext (resp. zext). Reported
and diagnosed by Sebastien Deldon.

Remove movePastCSLoadStoreOps and associated code for simple pointer
increments. Update routines that depended upon other opcodes for save/restore.
Adjust all testcases accordingly.

and testing is easier. A good example is the unknown-location.ll test that
now can just look for ".loc 1 0 0". We also don't use a DW_LNE_set_address for
every address change anymore.

later. Adjust a test that was looking for wrong code.

Would be good for a Linux person to review this.

It is generally not sufficient to check if the starting offset is in range
of the maximum offset that can be efficiently used for the target.

This makes it more clear that the symbol is an internal, compiler-generated
name and gives a little more description about its contents.
