Matt Arsenault 74742a1bb0 Fix assert with GEP ptr vector indexing structs
Also fix it calculating the wrong value. The struct index
is not a ConstantInt, so it was being interpreted as an array

Juergen Ributzka b4c2fa244a The vbroadcastsi256 intrinsic does not exactly resemble the GCC
builtin. The GCC builtin expects the arguments to be passed by val,
whereas the LLVM intrinsic expects a pointer instead.

This is related to PR 16581 and rdar:14747994.

Mark Lacey 9d8103de7a Auto-compute live intervals on demand.
When new virtual registers are created during splitting/spilling, defer
creation of the live interval until we need to use the live interval.

Along with the recent commits to notify LiveRangeEdit when new virtual
registers are created, this makes it possible for functions like
TargetInstrInfo::loadRegFromStackSlot() and
TargetInstrInfo::storeRegToStackSlot() to create multiple virtual
registers as part of the process of generating loads/stores for
different register classes, and then have the live intervals for those
new registers computed when they are needed.

Mark Lacey c3f912b945 Add the MachineInstrSpan class.
MachineInstrSpan is initialized with a MachineBasicBlock::iterator,
and is intended to track which instructions are inserted before/after
that instruction from the time the MachineInstrSpan is created.

It provides a begin()/end() interface to walk the range of
instructions inserted around the initial instruction (including that
initial instruction).

It also provides a getInitial() interface to return the initial
iterator.

Mark Lacey f367cd9239 Notify LiveRangeEdit of new virtual registers.
Add a delegate class to MachineRegisterInfo with a single virtual
function, MRI_NoteNewVirtualRegister(). Update LiveRangeEdit to inherit
from this delegate class and override the definition of the callback
with an implementation that tracks the newly created virtual registers.

Mark Lacey f9ea88546f Track new virtual registers by register number.
Track new virtual registers by register number, rather than by the live
interval created for them. This is the first step in separating the
creation of new virtual registers and new live intervals.  Eventually
live intervals will be created and populated on demand after the virtual
registers have been created and used in instructions.

Peter Collingbourne 68162e7512 DataFlowSanitizer: greylist is now ABI list.
This replaces the old incomplete greylist functionality with an ABI
list, which can provide more detailed information about the ABI and
semantics of specific functions.  The pass treats every function in
the "uninstrumented" category in the ABI list file as conforming to
the "native" (i.e. unsanitized) ABI.  Unless the ABI list contains
additional categories for those functions, a call to one of those
functions will produce a warning message, as the labelling behaviour
of the function is unknown.  The other supported categories are
"functional", "discard" and "custom".

- "discard" -- This function does not write to (user-accessible) memory,
  and its return value is unlabelled.
- "functional" -- This function does not write to (user-accessible)
  memory, and the label of its return value is the union of the label of
  its arguments.
- "custom" -- Instead of calling the function, a custom wrapper __dfsw_F
  is called, where F is the name of the function.  This function may wrap
  the original function or provide its own implementation.

Nick Lewycky c7776f737f Revert r187191, which broke opt -mem2reg on the testcases included in PR16867.
However, opt -O2 doesn't run mem2reg directly so nobody noticed until r188146
when SROA started sending more things directly down the PromoteMemToReg path.

In order to revert r187191, I also revert dependent revisions r187296, r187322
and r188146. Fixes PR16867. Does not add the testcases from that PR, but both
of them should get added for both mem2reg and sroa when this revert gets
unreverted.

Hans Wennborg d505fbf403 Options: Add new option kind that consumes remaining arguments
This adds KIND_REMAINING_ARGS, a class of options that consume
all remaining arguments on the command line.

This will be used to support /link in clang-cl, which is used
to forward all remaining arguments to the linker.

It also allows us to remove the hard-coded handling of "--",
allowing clients (clang and lld) to implement that functionality
themselves with this new option class.

Michael Gottesman 7a8017290a Update makeLibCall to return both the call and the chain associated with the libcall instead of just the call. This allows us to specify libcalls that return void.
LowerCallTo returns a pair with the return value of the call as the first
element and the chain associated with the return value as the second element. If
we lower a call that has a void return value, LowerCallTo returns an SDValue
with a NULL SDNode and the chain for the call. Thus makeLibCall by just
returning the first value makes it impossible for you to set up the chain so
that the call is not eliminated as dead code.

I also updated all references to makeLibCall to reflect the new return type.

Nick Lewycky 8d2e86db5a Fix an oversight in isPotentiallyReachable where we wouldn't do any CFG-walking

Refactor the code a little now that we need to fill to start the CFG-walking
algorithm with more than one starting basic block sometimes.

Special thanks to Andrew Trick for catching an error in my understanding of
natural loops in code review.

Shuxin Yang 76d082b5cd Misc enhancements to LTO:
1. Add some helper classes for partitions. They are designed in a
     way such that the top-level LTO driver will not see much difference 
     with or without partitioning.

  2. Introduce work-dir. Now all intermediate files generated during 
     LTO phases will be saved under work-dir. User can specify the workdir
     via -lto-workdir=/path/to/dir. By default the work-dir will be 
     erased before linker exit. To keep the workdir, do -lto-keep, or -lto-keep=1.

    TODO: Erase the workdir, if the linker exit prematurely.  
      We are currently not able to remove directory on signal. The support 
      routines simply ignore directory.

  3. Add one new API lto_codegen_get_files_need_remove().
     Linker and LTO plugin will communicate via this API about which files
    (including directories) need to removed before linker exit.

Chandler Carruth 912198585d Remove all checking for the various terminfo headers (term.h and
curses.h). Finding these headers is next to impossible. For example, on
Debian systems libtinfo-dev provides the terminfo reading library we
want, but *not* term.h. For the header, you have to use libncurses-dev.
And libncursesw-dev provides a *different* term.h in a different
location!

These headers aren't worth it. We want two functions the signatures of
which are clearly spec'ed in sys-v and other documentation. Just declare
them ourselves and call them. This should fix some debian builders and
provide better support for "minimal" debian systems that do want color
autodetection.
