  Log Message:
  -----------
  [TLS]: Clamp the alignment of TLS global variables if required by the target

Adding a module flag 'MaxTLSAlign' describing the maximum alignment a global TLS
variable can have. Optimizers are prevented from increasing the alignment of such
variables beyond this threshold.
