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.

[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.

[MinGW] Ignore the --enable-auto-import flag In GNU ld, this option is enabled by default, but can be set to reduce some warnings.
