2016-10-26erts: Avoid delayed fun undef raceSverker Eriksson
Avoid suspending fun caller not just if purge is already done but also if purge of another module has started. Another purge of the same module again cannot happen as making current to old transition includes thread progress.

2016-10-21erts: Use mprotect for hipe on all arch except x86_64Sverker Eriksson
Only x86_64 needs to reserve low virtual memory for its amd64 small code model.

2016-10-14erts: Cleanup hipe trampoline codeSverker Eriksson
2016-10-14erts: Remove dead alloc stats in hipe_amd64.cSverker Eriksson
erlang:system_info({allocator, exec_alloc}) have stats if we need it.
2016-10-14erts: Remove code_SUITE:make_stub and make_stub_many_funsSverker Eriksson
Hard to unit test now when it takes a magic HipeLoaderState as argument. All hipe testing should be enough exercise for code:make_stub_module.
2016-10-14erts: Let code:make_stub_module raise 'notsup'Sverker Eriksson
if hipe is disabled. Makes the code simpler to just ifdef away a lot of hipe stuff.
2016-10-14erts: Fix bug in stack walk on riscSverker Eriksson
Symptom: Got ra==NULL at nsp==nsp_end when running basic_SUITE:basic_arith on arm why has this not been detected before?
2016-10-14erts: Fix old leak for ppc hipe codeSverker Eriksson
* Use erts_alloc(ERTS_ALC_T_HIPE_EXEC,_) * Each module has its own trampolines
2016-10-14erts: Fix old leak for arm hipe codeSverker Eriksson
* Use erts_alloc(ERTS_ALC_T_HIPE_EXEC,_) * Each module has its own trampolines * Stubs do not use trampolines, they do their own long jumps.

2016-10-14erts: Enable exec_alloc for all hipe architecturesSverker Eriksson
For non-amd64 it's a "normal" allocator with a wrapper around mseg_alloc to call mprotect(PROT_EXEC).
2016-10-14erts: Remove debug printout for hipe loader stateSverker Eriksson
creation and destruction.
2016-10-14erts: Free hipe_refs and hipe_sdesc of a failed loadSverker Eriksson
2016-10-14erts: Refactor out hipe_purge_refs/sdescSverker Eriksson
from hipe_purge_module.
2016-10-14erts: Refactor hipe_loader_state_dtor into a true destructorSverker Eriksson
that is only called once. Basically switch hipe_free_loader_state and hipe_loader_state_dtor.
2016-10-14hipe,erts: Remove cached fun 'native_address'Sverker Eriksson
Did not work with purge and made worse by new purge strategy. Did yield terrible performance when fun thing is created *before* fun code is loaded. Like when receiving not yet loaded fun from other node. The cached 'native_address' in ErlFunThing will not be updated leading to mode switch and error_handler being called for every call to the fun from native code.
2016-10-14erts: Fix early hipe patch loadingSverker Eriksson
by introducing hipe_bifs:commit_patch_load/1 that creates the HipeModule.
