RFR (XXS): 8144690: g1Predictions.hpp includes allocation.inline.hpp

[Thomas Schatzl]

Hi all,

  we should not reference .inline.hpp files in .hpp files as per coding
standards. G1Predictions.hpp violates this, including
allocation.inline.hpp.

This patch fixes this problem simply by removing the offending include:
g1Predictions.hpp does not need allocations.inline.hpp at all.
