This reverts commit 7370ff624d217b0f8f7512ca5b651a9b8095a411. (and 47fb8ae2f9a4075de05433ef24f459b6befd1730). This commit broke the symbol type in import libraries generated for mingw autoexported symbols, when the source files were built with LTO. I'll commit a testcase that showcases this issue after the revert.

// This file provides a way to combine bitcode files into one COFF
|
|
// file by compiling them using LLVM.
|
|
//
|
|
// If LTO is in use, your input files are not in regular COFF files
|
|
// but instead LLVM bitcode files. In that case, the linker has to
|
|
// convert bitcode files into the native format so that we can create
|
|
// a COFF file that contains native code. This file provides that
|
|
// functionality.
