David Majnemer 07f7fe5a4c [COFF] Fix invalid alignment in tests 
Some COFF tests used INT_MIN for the alignment of the directive section.
This is invalid; replace the alignment with something more sensible: 1.

Rui Ueyama 251b0e268b COFF: Remove the old COFF linker and make link an alias to link2. 
It's time to remove old COFF linker because the new one is now complete.

Rui Ueyama 85225b0a36 COFF: Infer entry point as early as possible, but not too early. 
On Windows, we have four different main functions, {w,}{main,WinMain}.
The linker has to choose a corresponding entry point function among
{w,}{main,WinMain}CRTStartup. These entry point functions are defined
in the standard library. The linker resolves one of them by looking at
which main function is defined and adding a corresponding undefined
symbol to the symbol table.

Object files containing entry point functions conflicts each other.
For example, we cannot resolve both mainCRTStartup and WinMainCRTStartup
because other symbols defined in the files conflict.

Previously, we inferred CRT function name at the very end of name
resolution. I found that that is sometimes too late. If the linker
already linked one of these four archive member objects, it's too late
to change the decision.

The right thing to do here is to infer entry point name after adding
all symbols from command line files and before adding any other files
(which are specified by directive sections). This patch does that.
