[llvm-dev] LLVM-C.dll in LLVM release 10 seem to be incomplete/missing export directory

Hi David,
I tested rebuilding from source on windows, using the source archive on the
downlodpage. While the x64 target using cmake created a proper solution for
VS, the x86 target created a solution where some libs were not added as
dependency on the LLVM-C library and the LLVM-C.exports, too. In my
particular case LLVMGlobalISel and LLVMXCodeGen were not wired up
correctly. Once i had these builded separately, the final linking seemed to
not take any of the builded libs into account. On my system the x86 DLL was
9 kbytes, too. So in addition to the used host-triple, something else might
be broken. I haven't done anything with CMake yet, to give an answer on how
to fix it.
