exe_module should be renamed to elf_module and accompanied by a comment
indicating the chrome_elf.dll is where early process initialization happens.

Added this comment.
The crash reporting is handled by chrome_elf.dll which loads early in the chrome
process.

     return reinterpret_cast<GetCrashReportsPointer>(
         exe_module ? GetProcAddress(exe_module, "GetCrashReportsImpl")
                    : nullptr);
