  [LLD][COFF] Generate map file even if no /out flag is present

Currently LLD does not generate a map file if no /out flag (e.g., /out:a.exe) is
present. This is because LLD derives the map file's name from the default output
file name is no output file name is specified explicitly on the command
line. However, in this case, the default output file name has not been set by
LLD yet when LLD tries to set the name of the map file. This patch fixes this
corner case by moving the logic handling map file flags to a place after the
default output file name is set.
