Martin Storsjo 71663a2eac [MinGW] Don't pass -dynamicbase:no by default for arm/arm64
The linker refuses using -dynamicbase:no on these architectures.

Stop passing -dynamicbase (which just reinforces the lld-link
default) for simplicity.

Martin Storsjo b190fd2bb4 [MinGW] Implement the --[no-]gc-sections and --icf options
GNU ld doesn't seem to support --icf at all, but this was suggested
in D39885, and GNU gold seems to support it.

Martin Storsjo 094d8c09e6 [MinGW] Add support for --dynamicbase, ignore --nxcompat, --tsaware and --high-entropy-va
All of these are disabled by default in GNU ld, but enabled by default
in lld.

Disable dynamicbase by default since it potentially could cause
compatibility issues, but just ignore the others since the lld
default should be fine for most concievable cases.

Martin Storsjo 3c8d4b5a73 [MinGW] Handle --large-address-aware
In GNU ld, this option is only available on i386, not on x86_64
(where it's enabled by default with no option to disable it either).

Rui Ueyama 1f4cdcfec9 Accept not only --foo but also -foo.
GNU ld manual says that multi-letter long option can be prefixed with
either -- or -. Therefore, we should accept not only --subsystem but
also -subsystem, for example.

There is one exception. If an option starts with "o", it should only be
prefixed with -- to avoid ambiguity with -o<filename> option.

Martin Storsjo 2ba37d4b3e [MinGW] Only apply -Bstatic to following libraries
This is how the flag is documented in GNU binutils ld; -Bstatic
only applies to -l options after it, until the next -Bdynamic.

Martin Storsjo 31fe4cd25d [MinGW] Support dllexport on i386
In MinGW configurations (GCC, or clang with a *-windows-gnu target),
the -export directives in the object file contains the undecorated
symbol name, while it is decorated in MSVC configurations. (On the
command line, link.exe takes an undecorated symbol name for the
-export argument though.)

Martin Storsjo a79762a32d [MinGW] Map the -verbose option, implement -### for showing the produced parameters
Pass the -verbose option through to the COFF linker, and show the
arguments passed to it. If the -### option is specified, just show
the produced argument list and exit, just like in clang.

Replace the first argument with "lld-link" in order to produce a
correct command line.

Martell Malone 894dbbe8eb LLD: Introduce a GNU LD style driver for COFF
When building COFF programs many targets such as mingw prefer
to have a gnu ld frontend. Rather then having a fully fledged
standalone driver we wrap a shim around the LINK driver.

Extra tests were provided by mstorsjo
