Sometimes a copy from a vreg -> vreg sneaks into the middle of a terminator
sequence. It is safe to slice this into the stack protector success bb.
This fixes PR16979.

The recursive nature of the address selection code can cause the stack to
explode if there is a long chain of GEPs. Convert the recursive bit into a
iterative method to avoid this.

gcc doesn't support "gcc -m sse" and this was not tested in clang and only
used for link argument on darwin, so this was very likely just a bug.

This solves two problems:
1) MSBuild will not flag the build as unsuccessful just because we print
an error in the output, since "error(clang):" doesn't seem to match
the regex it's using.
2) It becomes more clear that the diagnostic is coming from clang as
supposed to cl.exe.

This doesn't change a lot since clang still thinks it knows all of the
-f*, -m* and -W* options for example.
Other than the options clang explicitly claims to know, this fixes pr9701.

We used to support both Windows and Unix style command line options. In Windows
style, an option and its value are separated by ":" (colon). In Unix, separator
is a space. Accepting both styles were convenient, but we can no longer allow
Unix style because I found that can be ambiguous.
For example, /nodefaultlib option takes an optional argument. In Windows style
it's going to be something like "/nodefaultlib:foo". There's no ambiguity what
"foo" means. However, if the option is "/nodefaultlib foo", "foo" can be
interpreted either an optional argument for "/nodefaultlib" or an input file
"foo.obj". We should just stop accepting the non-standard command line style.

The underlying type of all plain enums in MSVC is 'int', even if the
enumerator contains large 32-bit unsigned values or values greater than
UINT_MAX. The only way to get a large or unsigned enum type is to
request it explicitly with the C++11 strong enum types feature.
However, since LLVM isn't C++11 yet, I had to add a conditional
LLVM_ENUM_INT_TYPE to Compiler.h to control its usage.
The motivating true positive for this change is compiling PointerIntPair
with MSVC for win64. The PointerIntMask value is supposed to be pointer
sized value of all ones with some low zeros. Instead, it's truncated to
32-bits! We are only saved later because it is sign extended back in
the AND with int64_t, and we happen to want all ones.
This silences lots of -Wmicrosoft warnings during a clang self-host
targeting Windows.

These options are to enable DLL delay loading. If enabled, DLL is loaded
at run time by a helper routine when a function in the DLL is actually called
for the first time, instead of making the Windows loader to load all DLLs at
startup time. This should shorten startup delay if an executable have many
imported symbols.
The linker needs to create a "delayed import table" and link delayimp.lib in
which helper functions are defined to support the feature.
For now, we just ignore the options, so that the linker does not complain when
it sees these options. We want to support them in the future.

a) Make sure we are emitting the correct section in our section labels
when we begin the module.
b) Make sure we are emitting the correct pubtypes section in the
presence of gnu pubtypes.
c) For C++ struct, union, class, and enumeration types are default
external.

Summary:
This patch changes WriterPECOFF to actually write down the address instead of ignoring it.
Also, it changes the order of adding the BaseReloc chunk as otherwise the address wasn't set yet.
I think a better way of doing it would be to change DataDirectoryAtom to create a Reference
instead of using a number, and to change IdataPass accordingly, but I'm not sure how to do that.

This patch also fixes the case where a compilation database is autodetected from
source but the file itself cannot be found in the compilation database, it then
ignores the compilation database and transforms the file with c++11 support.

Summary: This patch changes WritePECOFF to calculate the value of the SizeOfHeaders PE header field instead of just using 512.
