    Fix #15953 by consistently using dumpIfSet_dyn to print debug output · dcf1f926
    Chaitanya Koparkar authored
    In some modules we directly dump the debugging output to STDOUT
    via 'putLogMsg', 'printInfoForUser' etc. However, if `-ddump-to-file`
    is enabled, that output should be written to a file. Easily fixed.
    Certain tests (T3017, Roles3, T12763 etc.) expect part of the
    output generated by `-ddump-types` to be in 'PprUser' style. However,
    generally we want all other debugging output to use 'PprDump'
    style. `traceTcRn` and `traceTcRnForUser` help us accomplish this.
    This patch also documents some missing flags in the users guide.
