gcc::jit::recording::union_ has some stray fields, which
are duplicates of those in the compound_type base class.
It looks like these have been present since the initial merger of the jit
branch to trunk (r217374), where it had three duplicate fields:
location *m_loc;
string *m_name;
fields *m_fields;
I removed the duplicate field "m_fields" in r219564 but missed the other
two.
This patch removes them.
gcc/jit/ChangeLog:
PR jit/81672
* jit-recording.h (gcc::jit::recording::union_): Remove fields
"m_loc" and "m_name".
