lld, llvm-dlltool, llvm-lib: Use getAsString() instead of getSpelling() for printing unknown args Since OPT_UNKNOWN args never have any values and consist only of spelling (and are never aliased), this doesn't make any difference in practice, but it's more consistent with Arg's guidance to use getAsString() for diagnostics, and it matches what clang does.

Recommit of r263252, [ELF] - Change all messages to lowercase to be consistent. 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.

# UNKNOWN: unknown emulation: foo
This reverts the r263125 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.

[ELF] Fail the link early if an output path is invalid 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. Differential Revision: https://reviews.llvm.org/D30449 llvm-svn: 297645

[ELF] - Exit on --version call. 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.

# RUN: ld.lld --version 2>&1 | FileCheck -check-prefix=VERSION %s
Make the behavior of the -v option more closer to GNU linkers. Previously, lld exited with an error status if the only option given to the command was -v. GNU linkers gracefully exit in that case. This patch makes lld behave like GNU. Note that even with this patch, lld's -v and --version options behave slightly differently than GNU linkers' counterparts. For example, if you run `ld.bfd -v -v`, the version string is printed out twice. But that is an edge case that I don't think we need to take care of.
