[cfe-dev] "File too big/too many sections" when building Registry.cpp in MSYS2 Environment

[William D. Jones via cfe-dev]

Did you cross-compile for MinGW? I've noticed that with the new change, 
native compile, Registry.cpp now compiles, but attempting to link
bin\clangDynamicASTMatchers.dll causes a link step that takes over 90 
minutes (!!) before bombing with an excessive number of undefined symbols. 
So many, that I cannot even copy and paste them all from my scrollback. The 
linker cannot find any of the symbols from Registry.cpp.

It is dawning on me that building a Debug build of Clang/LLVM on Windows is 
impractical/development seems to mainly be done w/ gold on Linux to avoid 
linker woes.

Sorry for the delay. I noticed that you pass the assembler options for only
64-bit builds. Is there any harm for enabling the flags for 32-bit builds as
well? The 64-bit MinGW build appears to be broken on my machine (gcc 5.3.0);
LTO.dll spent 30 minutes compiling before I manually disabled the build.

To follow up, r290358 should fix this.
