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.

The size of common symbols is now tracked correctly, so they can be listed in the arange section without needing knowledge of other following symbols.

.comm (and .lcomm) do not indicate to the system assembler any particular section to use, so we have to treat them as having no section.

Test case update to account for this.

This is a small step that may enable some simplifications in producer
(DWARFContext) and consumer (DWARFCompileUnit and other places) by
making a more complete abstraction around the data and relocations for a
section. Small initial steps could include simple changes such as
passing the pair to DWARFCompileUnit's ctor rather than passing the data
and relocs separately. I don't intend to pursue any such changes
immediately, however.

The motivation for doing this now is that type unit dumping will need to
deal with these data+reloc pairs moreso than the existing dumping
support has needed to associate the data as type unit sections are named
the same (debug_types) and comdat group folded. So to implement dumping
and reloc handling we'll need a mapping of section->data+relocs.

Revert 191122 - with extra checks we are allowed to vectorize math library
function calls.

Standard library indentifiers are reserved names so functions with external
linkage must not overrided them. However, functions with internal linkage can.

Therefore, we can vectorize calls to math library functions with a check for
external linkage and matching signature. This matches what we do during
SelectionDAG building.

Overflow doesn't affect the correctness of equalities. Computing this is cheap,
we just reuse the computation for the inbounds case and try to peel of more
non-inbounds GEPs. This pattern is unlikely to ever appear in code generated by
Clang, but SCEV occasionally produces it.

Changes to MIPS SelectionDAG:
* Added nodes VEXTRACT_[SZ]EXT_ELT to represent extract and extend in a single
  operation and implemented the DAG combines necessary to fold sign/zero
  extends into the extract.
