Jakob Stoklund Olesen 024d7ae110 Add a static MachineOperand::clobbersPhysReg().
It can be necessary to detach a register mask pointer from its
MachineOperand. This method is convenient for checking clobbered
physregs on a detached bitmask pointer.

Jakob Stoklund Olesen a16ae59722 Add register mask support to InterferenceCache.
This makes global live range splitting behave identically with and
without register mask operands.

This is not necessarily the best way of using register masks for live
range splitting.  It would be more efficient to first split global live
ranges around calls (i.e., register masks), and reserve the fine grained
per-physreg interference guidance for global live ranges that do not
cross calls.

For now the goal is to produce identical assembly when enabling register
masks.

Douglas Gregor a1bffa26ca Allow implicit capture of 'this' in a lambda even when the capture
default is '=', and reword the warning about explicitly capturing
'this' in such lambdas to indicate that only explicit capture is
banned. 

Introduce Fix-Its for this and other "save the programmer from
themself" rules regarding what can be explicitly captured and what
must be implicitly captured.

Douglas Gregor 01db64f0ac Add test from [expr.prim.lambda]p12, which deals with odr-use and
nested captures. We currently don't get odr-use correct in array
bounds, so that bit is commented out while we sort out what we need to
do.

Douglas Gregor 04bbab586b Don't introduce a lambda's operator() into the class until after we
have finished parsing the body, so that name lookup will never find
anything within the closure type. Then, add this operator() and the
conversion function (if available) before completing the class.

Hal Finkel 1bde3f86d1 Update BBVectorize to use aliasesUnknownInst.

alias sets. This is important to prevent instruction fusing from reordering
function calls. Resolves PR11920.

Duncan Sands bf48ac622a Revert commit 149912 (lattner) and add a testcase that shows the problem (which
is that patterns no longer match for vectors of booleans, because you only get
ConstantDataVector when the vector element type is i8, i16, etc, not when it is
i1).  Original commit message:
Remove some dead code and tidy things up now that vectors use ConstantDataVector
instead of always using ConstantVector.

Richard Smith 63168c7533 PR11684, core issue 1417:
o Correct the handling of the restrictions on usage of cv-qualified and
  ref-qualified function types.
o Fix a bug where such types were rejected in template type parameter default
  arguments, due to such arguments not being treated as a template type arg
  context.
o Remove the ExtWarn for usage of such types as template arguments; that was
  a standard defect, not a GCC extension.
o Improve the wording and unify the code for diagnosing cv-qualifiers with the
  code for diagnosing ref-qualifiers.

Richard Smith 5e580292ac Track whether a function type has a trailing return type as type sugar. Use this
to pretty-print such function types better, and to fix a case where we were not
instantiating templates in lexical order. In passing, move the Variadic bit from
Type's bitfields to FunctionProtoType to get the Type bitfields down to 32 bits.
Also ensure that we always substitute the return type of a function when
substituting explicitly-specified arguments, since that can cause us to bail
out with a SFINAE error before we hit a hard error in parameter substitution.

David Blaikie 54f5d859ad Move -Wswitch from -Wmost to -Wall, consitent with GCC.
This is a relatively noisy warning for a codebase not explicitly designed for
it (effectively enforcing a stylistic constraint about the use of defaults
in switches over enums) & there's nothing Clang does to clean up the noise
when compared to GCC's implementation so the same decision seems suitable.

Andrew Trick d3f8fe81f4 RegAlloc superpass: includes phi elimination, coalescing, and scheduling.
Creates a configurable regalloc pipeline.

Ensure specific llc options do what they say and nothing more: -reglloc=... has no effect other than selecting the allocator pass itself. This patch introduces a new umbrella flag, "-optimize-regalloc", to enable/disable the optimizing regalloc "superpass". This allows for example testing coalscing and scheduling under -O0 or vice-versa.

When a CodeGen pass requires the MachineFunction to have a particular property, we need to explicitly define that property so it can be directly queried rather than naming a specific Pass. For example, to check for SSA, use MRI->isSSA, not addRequired<PHIElimination>.

CodeGen transformation passes are never "required" as an analysis

ProcessImplicitDefs does not require LiveVariables.

We have a plan to massively simplify some of the early passes within the regalloc superpass.
