After building vibe.d in dmd 2.064 beta 1 as a lib I was not able to 
link it with application. It was working in dmd 2.063. Now I get:

Error 1: Previous Definition Different : _D12__entrypoint12__ModuleInfoZ

I was not able to build absolutely minimal test case but you can download
linked file where you will find prebuild libs using dmd 263 and 264, including
source and .bat to rebuild them. Also small app that just links the file. You
can find the build scripts for both compiler veresions are identical, yet the
.lib fails to link when build and linked with dmd 264. Also invalid executable
is generated.

Description of folders:

* VibeLink is test app just to link vibe*.lib file
* vibe-d is latest stable release

* VibeLink\build_263.bat
    run this to link with prebuild VibeLink\lib\vibe_dmd263_snn.lib using dmd
2.063

* VibeLink\build_264.bat
    run this to link with prebuild VibeLink\lib\vibe_dmd264beta1.lib using dmd
2.064

* vibe-d\build.bat
    run this to rebuild vibe.lib

fix Issue 11251 - Not able to link (Previous Definition Different)


But, the codegen generates ModuleInfo symbol for the module. And vibe.d has its
own main function in library. Then, compiling uer progam with vibe.d library
will cause the conflict of two ModuleInfo symbols of __entrypoint module.

Due to avoid ModuleInfo symbol generation for __entrypoint, I added a special
case in Module::genobjfile function. But, I'm not sure that the change won't
cause any other problems...
