b28f31e7ed Split out cold code path in newImpl
I noticed that the whole newImpl is inlined. Since OOM handling code is
rarely executed, we should only inline the hot path.

22366518b7 Move CPP_PROLOGUE and CPP_EPILOGUE to the .cpp
This lets us avoid having to specify them in every C file.

743d940dc3 Header refactoring: Split up jemalloc_internal.h
This is a biggy.  jemalloc_internal.h has been doing multiple jobs for a while
now:
- The source of system-wide definitions.
- The catch-all include file.
- The module header file for jemalloc.c

This commit splits up this functionality.  The system-wide definitions
responsibility has moved to jemalloc_preamble.h.  The catch-all include file is
now jemalloc_internal_includes.h.  The module headers for jemalloc.c are now in
jemalloc_internal_[externs|inlines|types].h, just as they are for the other
modules.

2319152d9f jemalloc cpp new/delete bindings
Adds cpp bindings for jemalloc, along with necessary autoconf settings.
This is mostly to add sized deallocation support, which can't be added
from C directly.  Sized deallocation is ~10% microbench improvement.

* Import ax_cxx_compile_stdcxx.m4 from the autoconf repo, seems like the
  easiest way to get c++14 detection.
* Adds various other changes, like CXXFLAGS, to configure.ac.
* Adds new rules to Makefile.in for src/jemalloc-cpp.cpp, and a basic
  unittest.
* Both new and delete are overridden, to ensure jemalloc is used for
  both.
* TODO future enhancement of avoiding extra PLT thunks for new and
  delete - sdallocx and malloc are publicly exported jemalloc symbols,
  using an alias would link them directly.  Unfortunately, was having
  trouble getting it to play nice with jemalloc's namespace support.

Testing:
Tested gcc 4.8, gcc 5, gcc 5.2, clang 4.0.  Only gcc >= 5 has sized
deallocation support, verified that the rest build correctly.

Tested mac osx and Centos.

Tested --with-jemalloc-prefix and --without-export.

This resolves #202.
