Jakob Stoklund Olesen 1ac7e662d4 Enable SandyBridgeModel for all modern Intel P6 descendants.
All Intel CPUs since Yonah look a lot alike, at least at the granularity
of the scheduling models. We can add more accurate models for
processors that aren't Sandy Bridge if required. Haswell will probably
need its own.

The Atom processor and anything based on NetBurst is completely
different. So are the non-Intel chips.

Hal Finkel 567fa62ddc Restore real bit lengths on PPC register numbers
As suggested by Bill Schmidt (in reviewing r178067), use the real register
number bit lengths (which is self-documenting, and prevents using illegal
numbers), and set only the relevant bits in HWEncoding (which defaults to 0).

No functionality change intended.

Enrico Granata b65b3030b6 <rdar://problem/13339196>
The algorithm to access an item in a __NSArrayM was not reacting properly to deletions
The fix is to use a smarter formula that accounts for items shifting and the resulting notion of offsets in the table

Howard Hinnant 5a13d8dcea Tighten up the iterator requirements for the vector member templates. This is especially important for the constructors so that is_constructible<vector<T>, I, I> gives the right answer when T can not be constructed from *I. Test case included for this latter point.

Hal Finkel 1fa2f945ea Fix the register scavenger for targets that provide custom spilling
As pointed out by Richard Sandiford, my recent updates to the register
scavenger broke targets that use custom spilling (because the new code assumed
that if there were no valid spill slots, than spilling would be impossible).

I don't have a test case, but it should be possible to create one for Thumb 1,
Mips 16, etc.

Hal Finkel feea653974 PPC: Use HWEncoding and TRI->getEncodingValue
As pointed out by Jakob, we don't need to maintain a separate
register-numbering table. Instead we should let TableGen generate the table for
us from the information (already present) in PPCRegisterInfo.td.
TRI->getEncodingValue is now used to access register-encoding values.

No functionality change intended.

Hal Finkel 0dfbb05aff Use multiple virtual registers in PPC CR spilling
Now that the register scavenger can support multiple spill slots, and PEI can
use virtual-register-based scavenging for multiple simultaneous registers, we
can use a virtual register for the transfer register in the CR spilling code.

This should eliminate the last place (outside of the prologue/epilogue) where
we depend on the unconditional availability of the r0 register. We will soon be
able to allocate it (in a somewhat restricted sense) as a GPR.

Hal Finkel d8a423cd71 Update PPCRegisterInfo's use of virtual registers to be SSA
PPC's use of PEI's virtual-register-based scavenging functionality had
redefined the virtual registers (it was non-SSA). Now that PEI supports
dealing with instructions with multiple virtual registers, this can be
cleanup up to use multiple virtual registers and keep SSA form.

No functionality change intended.

Hal Finkel 4e05788cc3 Update PEI's virtual-register-based scavenging to support multiple simultaneous mappings
The previous algorithm could not deal properly with scavenging multiple virtual
registers because it kept only one live virtual -> physical mapping (and
iterated through operands in order). Now we don't maintain a current mapping,
but rather use replaceRegWith to completely remove the virtual register as
soon as the mapping is established.

In order to allow the register scavenger to return a physical register killed
by an instruction for definition by that same instruction, we now call
RS->forward(I) prior to eliminating virtual registers defined in I. This
requires a minor update to forward to ignore virtual registers.

These new features will be tested in forthcoming commits.

Now all x86 instructions that have itinerary classes also have SchedRW

Arnold Schwaighofer aadf10435a BasicAA: Only query twice if the result of the more general query was MayAlias
This is a compile time optimization. Before the patch we would do two traversals
on each call to aliasGEP - one with a set size parameter one with UnknownSize.
We can do better by first checking the result of the alias query with
UnknownSize.
Only if this one returns MayAlias do we query a second time using size and type.

This recovers an about 7% compile time regression on spec/ammp.

Enrico Granata 9fb5ab558b Our commands that end up displaying a ValueObject as part of their workflow use OptionGroupValueObjectDisplay as their currency for deciding the final representation
ValueObjects themselves use DumpValueObjectOptions as the currency for the same purpose

Argyrios Kyrtzidis b6210dff97 [Preprocessor/Modules] Separate the macro directives kinds into their own MacroDirective's subclasses.
For each macro directive (define, undefine, visibility) have a separate object that gets chained
to the macro directive history. This has several benefits:

-No need to mutate a MacroDirective when there is a undefine/visibility directive. Stuff like
 PPMutationListener become unnecessary.
-No need to keep extra source locations for the undef/visibility locations for the define directive object
 (which is the majority of the directives)
-Much easier to hide/unhide a section in the macro directive history.
-Easier to track the effects of the directives across different submodules.

Reid Kleckner e7e64d8a7b [ms-cxxabi] Mangle vector types
Summary:
The only vector types a user can pass from MSVC code to clang code are
the ones from *mmintrin.h, so we only have to match the MSVC mangling
for these types.  MSVC mangles the __m128 family of types as tag types,
which we match.  For other vector types, we emit a unique tag type
mangling that won't match anything produced by MSVC.
