[cfe-dev] Linking libclang.dll out of memory with MSVC

[John Sully via cfe-dev]

Are you building for 32-bits?  By default that uses the 32-bit toolchain
and you're likely running out of address space - especially if you use
LTCG.  You can build with the 64-bit compiler (and still output 32-bits)
which should fix your issue.
