primarily intended for miuse of @selector expression.
But warning is too noisy and will be issued when
an actual @selector is used. // rdar://15740134

A[i * Stride1] += B[i * Stride2];
We take loops like this and check that the symbolic strides 'Strided1/2' are one
and drop to the scalar loop if they are not.
This is currently disabled by default and hidden behind the flag
'enable-mem-access-versioning'.

An upcoming loop vectorizer commit will want to replace a SCEVUnknown(Value*)
by a SCEVConstant. This commit modifies the SCEVParameterRewriter to support
this. The SCEVParameterRewriter constructor can optionally specify to follow
this behavior.

The disassembler would no longer be able to disambiguage between the two
variants (explicit immediate #0 vs implicit, omitted #0) for the ldrt, strt,
ldrbt, strbt mnemonics as both versions indicated the disassembler routine.

With this change tok::code_completion is finally handled exclusively as a
special token kind like other tokens that need special treatment.
All callers have been updated to use the specific token consumption methods and
the parser has a clear idea the current token isn't special by the time
ConsumeToken() gets called, so this has been unreachable for some time.
ConsumeAnyToken() behaviour is unchanged and will continue to support
unexpected code completion as part of the special token path.
This survived an amount of fuzzing and validation, but please ping the list if
you hit a code path that previously relied on the old unexpected handler and
now asserts.

Based on recent discussions, attempt to provide a clearer distinction between
MicrosoftMode and MicrosoftExt. This still doesn't feel perfect but gives a
better idea which is which.
Also update the CPlusPlus11 description which got missed in r171367.

Module-definition (.def) files are the file containing linker directives,
such as export symbols. Because link.exe supports the same features as command
line options, just as some Linker Script commands overlaps with command line
options, use of module-definition file is not really necessary. It provides
an alternative way to specify some linker options.
This patch implements EXPORTS directive. Other directives will be implemented
in the future.

Before:
SomeMap[std::pair(aaaaaaaaaaaa, bbbbbbbbbbbbbbb)]
.insert(ccccccccccccccccccccccc);
After:
SomeMap[std::pair(aaaaaaaaaaaa, bbbbbbbbbbbbbbb)].insert(
ccccccccccccccccccccccc);
This seems to be about 3:1 more common in Google and Chromium style and I found
only a handful of instances inside the LLVM codebase.

The GNU assembler supports prefixing the expression with a '#' to indiciate that
the value that is being moved is infact a constant. This improves the
compatibility of the integrated assembler's parser for this.

The GNU assembler has an extension that allows for the elision of the paired
register (dt2) for the LDRD and STRD mnemonics. Add support for this in the
assembly parser. Canonicalise the usage during the instruction parsing from
the specified version.

The ARM ARM indicates the mnemonics as follows:
ldrbt{<c>}{<q>} <Rt>, [<Rn>], {, #+/-<imm>}
ldrt{<c>}{<q>} <Rt>, [<Rn>] {, #+/-<imm>}
strbt{<c>}{<q>} <Rt>, [<Rn>] {, #<imm>}
strt{<c>}{<q>} <Rt>, [<Rn>] {, #+/-<imm>}
This improves the parser to deal with the implicit immediate 0 for the mnemonics
as per the specification.
Thanks to Joerg Sonnenberger for the tests!

__declspec(align), when applied to bitfields affects their perferred
alignment instead of their required alignment. We don't know why.
Also, #pragma pack(n) turns packing *off* if n is greater than the
pointer size. This is now observable because of the impact of
declspec(align) on bitfields.

I previously fixed a bug in the SocketAddress class where SocketAddress::GetPort() wasn't using ntohs() on the port number in the structures.
After fixing this, it broke places where we weren't using ntohs() and htons() correctly.

The MS abi lays out *all* non-virtual bases with leading vfptrs before
laying out non-virutal bases without vfptrs. This guarantees that the
primary base is laid out first. r198818 fixed RecordLayoutBuilder to
produce compatiable layouts. This patch fixes CGRecordLayoutBuilder to
be able to consume those layouts and produce meaningful output without
tripping any asserts about assumed incoming layout.
A test case is included that shows CGRecordLayoutBuilder in fact
produces output in the compatiable order.
