RFR (XXS): 8131344: Missing klass.inline.hpp include in compiler files

[Thomas Schatzl]

Hi all,

  while working on changes for PLAB handling improvements I found that
with these changes compilation would not be successful any more due to
some compiler code missing some includes to oops/Klass.inline.hpp
because of the use of the Klass::encode_klass() method.

This change adds the additional includes to these files.

I intend to push this through the hs-rt tree since all other changes
will be pushed through that tree, but it changes compiler files only, so
I have it out for review here.
