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!

This reverts commit r198865 which reverts r198851.
ASan identified a use-of-uninitialized of the DwarfTypeUnit::Ty variable
in skeleton type units.

__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.

property has the naming convention that implies 'ownership'.
2) improve on diagnostic and make it property specific.
3) fix the line number in the case of default property
synthesis. // rdar://15757510

Original commit message:
PR18427: Use an appropriately-aligned buffer in APValue, to avoid a crash on
SPARC, where uint64_t apparently requires higher alignment than void*.

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.

Preserves the setting of -fretain-comments-from-system-headers when
building/saving/loading module files. This allows code completion to pick up
documentation comments from system modules.

Fixes <rdar://problem/15596883>
In ARC, __attribute__((objc_precise_lifetime)) guarantees that the
object stored in it will survive to the end of the variable's formal
lifetime. It is therefore useful even if it completely unused.

I would not normally add tests like these, but the copy constructor is not
used at all in our codebase with c++11, so having this tests might prevent
breaking the c++03 build again.

To declare or define reserved identifers is undefined behaviour in standard
C++. This needs to be addressed in compiler-rt before it can be used in LLVM.
See the list discussion for details.
This reverts commit r198858.
