[PECOFF] Process Import Name/Type field in the import library. This patch removes hacky mangle() function, which strips all decorations uncondtitionally. LLD now interprets Import Name/Type field in the import library properly as described in the Microsoft PE/COFF Spec. llvm-svn: 187388

# Verify that lld can handle .lib files. "main.obj" refers "var" and
# "fn" defined in "vars.lib".
[PECOFF] Implement the reader for the import library. This is the first patch toward full DLL support. With this patch, lld can read .lib file for a DLL. Reviewers: Bigcheese CC: llvm-commits Differential Revision: http://llvm-reviews.chandlerc.com/D987 llvm-svn: 184101

[PECOFF] Support linking against DLL. This patch adds a new pass, IdataPass, to transform shared atom references to real references and to construct the .idata section data. With this patch lld can produce a working Hello World program by linking it against kernel32.dll and user32.dll.

[PECOFF] Emit the import table to .idata section. Emitting idata atoms to their own section would make debugging easier. The Windows loader do not really care about whether the DLL import table is in .rdata or its own .idata section, so there is no change in functionality. llvm-svn: 196458
