This is to improve compatibility with GNU Libtool that expect
/supported targets:.* elf/ in a message for the -help option.

Patch from James Henderson.
If a user has a long link, e.g. due to a large LTO link, they do not
wish to run it and find that it failed because there was a mistake in
their command-line, after they waited for some significant amount of
time. This change adds some basic checking of the linker output file
path, which is run shortly after parsing the command-line and linker
script. An error is emitted if LLD cannot write to the specified path.

GNU linkers disagree here.
Though both -version and -v are mentioned
in help to print the version information, GNU ld just normally exits,
while gold can continue linking. We are compatible with ld.bfd here.
This fixes PR31057.

Usually, options that are longer than one character can be preceded
either by "-" or "--", but options starting with "o" are exceptions
because they conflict with "-o" option. They have to be preceded by
"--".

--pic-executable
Create a position independent executable. This is currently only
supported on ELF platforms. Position independent executables are
similar to shared libraries in that they are relocated by the
dynamic linker to the virtual address the OS chooses for them
(which can vary between invocations). Like normal dynamically
linked executables they can be executed and symbols defined in the
executable cannot be overridden by shared libraries.

which was reverted because included
unrelative changes by mistake.
Original commit message:
[ELF] - Change all messages to lowercase to be consistent.
That is directly opposite to http://reviews.llvm.org/D18045,
which was reverted.
This patch changes all messages to start from lowercase letter if
they were not before.
That is done to be consistent with clang.

It was discussed to make all messages be
lowercase to be consistent with clang.
(also reverts the r263128 which fixed
build bot fail after r263125)
Original commit message:
[ELF] - Consistent spelling for error/warning messages
Previously error and warnings were not consistent in lld.
Some of them started from lowercase letter, others from
uppercase. Also there was one or two which had a dot at the end.
This patch changes all messages to start from uppercase letter if
they were not before.

On some Windows environment, this test did not fail, because opening NUL
with FileOutputBuffer didn't fail. Thanks to George Rimar for reporting.

It can fail to open an output file for various reasons, including
lack of permission, too long filename, or the output file is not
a mmap'able file.
