There should be no GCs between Instructions::New and
all write into the instructions object, because GC indiscriminately
write protects all code objects at the end of the GC.
In the previous version of the code assembler->GetCodeComments would
potentially trigger a GC and the code would crash trying to write
pointers into the code.
Also move FlushICache to the point after everything is written
into the code object.
Fixes#34030
