[PATCH] Don't use /implib when linking LLVM executables

[Adrian McCarthy]

Hi chandlerc,

No import library is actually generated when linking the executables.  Note that there was already code to do this for cywin and mingw.

This is a step toward eliminating the apparent circular dependency:  lldb.lib (the fake import library) depends on lldb.exe, which depends on lldb.lib (the actual import library for (lib)lldb.
