Tell lit.cfg about more Windows triples

[Gao, Yunzhong]

Hi,

Due to bug#17463, there is code in llvm/test/lit.cfg to append elf to the host triple when running lli

tests on Windows. However, the host triple on my 64-bit PC is x86_64-pc-windows-msvc, so it does

not match any of the expected patterns. I am wondering if it makes sense to make the following

change to lit.cfg, although, it does have the effect of creating a strange -windows-msvc-elf triple.

What do you think?
