Subject: [PATCH] Handle addresses larger than 2 GB for MinGW builds

Before this commit, the default memory limit was around 2 GB and
our MinGW built executables hit this limit. Swift and all 3rd party
libraries are 64 bit safe, so it is also safe to use the
large-address-aware linker flag. This allows memory allocation up
to 4 GB.
