This patch inverts the return value of these functions, so that they return
"true" on success and "false" on failure. The meaning of boolean return value
was mixed in LLD; for example, InputGraph::validate() returns true on success.
With this patch they'll become consistent.

/PDBALTPATH:<path> is an option to embed a different path for the PDB file to
the binary than the actual PDB file location. Because we don't support PDB
file, we'll just ignore the option for now.

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.

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.

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.

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

This adds an option --output-filetype that can be set to either
YAML/Native(case insensitive). The linker would create the outputs
associated with the type specified by the user.

Changes all the tests to use the new option.

GNU LD driver only understood no_such_file_or_directory error and was showing
just "Unknown Error" for any other type of error. With this patch, the driver
now prints file name and error message string by default.

/incremental is an option to enable incremental linking. We will eventually
want to implement the feature for better performance, but in the meantime,
we want to just ignore the option so that the linker does not output unknown
option error when it sees /incremental option.

/errorReport is a command line option to let the linker to report internal
linker error information to Microsoft. For LLD that option doesn't make any
sense, so it just ignores the option.

Base relocation block should be aligned on a 32-bit boundary. While the PECOFF
spec mentions only aligning the blocks, and not padding them, link.exe seems
to add an extra IMAGE_REL_I386_ABSOLUTE entry (just a zeroed WORD) in order to
pad the blocks.

This sets the sectionChoice property for DefinedAtoms. The output section name
is derived by the property of the atom. This also decreases native file size.

Adds a test.

This patch changes lld to go through all sections while calculating the size
for SizeOfCode, SizeOfInitializedData and SizeOfUninitializedData fields in the
PE header, instead of using only a small set of hard-coded sections.

This only really changes SizeOfInitializedData which didn't include .reloc
section before this patch.
