COFF: Fix import thunks and name mangling for x86. With this patch, LLD is now able to correctly link a "hello world" program written in assembly for 32-bit x86. llvm-svn: 241771

# RUN: lld-link %t.obj %p/Inputs/std32.lib /subsystem:console \
COFF: support the /appcontainer flag The /appcontainer flag indicates that the module may only be used inside an application container (for isolation). This has been supported by link.exe since Windows 8.0. It sets an additional bit in the PE DLL Characteristics flag to indicate the behavioural change. llvm-svn: 299728

COFF: Implement base relocations for x86. With this patch, LLD is now able to self-link an .exe file for x86 that runs correctly, although I don't think some headers (particularly SEH) are not correct. DLL support is coming soon. llvm-svn: 241857

Merge IAT and ILT. Previously, LLD-produced executables had IAT (Import Address Table) and ILT (Import Lookup Table) as separate chunks of data, although their contents are identical. My interpretation of the COFF spec when I wrote the COFF linker is that they need to be separate tables even though they are the same. But Peter found that the Windows loader is fine with executables in which IAT and ILT are merged. This is a patch to merge IAT and ILT. I confirmed that an lld-link self-hosted with this patch works fine. Fixes https://bugs.llvm.org/show_bug.cgi?id=33064 Differential Revision: https://reviews.llvm.org/D33326 llvm-svn: 303374
