[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.

CHECK: Disassembly of section .text:
[PECOFF] Trim at most one character from imported symbols. The import name is not always the same as the symbol name. If the name/type field in the import header is NOPREFIX or UNDECORATE, we need to strip some characters from symbol to get its import name. The Microsoft PE/COFF spec is vague if symbol contains more than two consecutive characters to be stripped. We used to strip all characters, but it doesn't seem right as we couldn't link against the system library because of this name mangling. Looks like we shouldn't strip more than one character. llvm-svn: 188154

CHECK-NEXT: .text:
[PECOFF] Add a generic section writer. Instead of having multiple SectionChunks for each section (.text, .data, .rdata and .bss), we could have one chunk writer that can emit any sections. This patch does that -- removing all section-sepcific chunk writers and replace them with one "generic" writer. This change should simplify the code because it eliminates similar-but- slightly-different classes. It also fixes an issue in the previous design. Before this patch, we could emit only limited set of sections (i.e. .text, .data, .rdata and .bss). With this patch, we can emit any sections. llvm-svn: 195797
