RFR (XS) 8223617: code_size2 needs adjustments

[Schmelter, Ralf]

Hi,

on my Skylake Windows machine the current jdk/jdk fails with the following assertion:

#  Internal Error (c:/priv/hg/openjdk/src/hotspot/share/runtime/stubRoutines.cpp:279), pid=42504, tid=131676
#  assert(code_size2 == 0 || buffer.insts_remaining() > 200) failed: increase code_size2

After increasing the code size by 200 bytes, the assertion vanishes.

Best regards,
