2014-01-22erts: Fix crash when comparing very large floats with integersSverker Eriksson
big_buf was one word too short on 32-bit emulators causing memory corruption. Seems like this did not cause a problem before the ESTACK memory layout was changed in 172ebf11dc455e22b87f.
2014-01-22erts: Refactor big-float compare on HALFWORD to use C-stackSverker Eriksson
for the temporary conversion from float to big. Preparation for coming bugfix of 'big_buf' array size.

2014-01-17erts: Refactor ESTACK & WSTACK to use a struct easy to "export"Sverker Eriksson
This is not a clean refactor. It changes the behaviour slightly of E/WSTACK_RESTORE. The allocated stack from E/WSTACK_SAVE is used as-is and not copied into default_stack. This will hopefully fix an illusive memory leak that valgrind is reporting.

2014-01-10erts: Make sure fds 0,1 and 2 are openLukas Larsson
If they are not open a really nasty race where the io pipe in erl_poll got fd 0 and the fd_driver setting fd 0 to blocking could occur. This caused the emulator to hang during shutdown.
2014-01-10erts: Run binary_SUITE:trapping even for 32bitSverker Eriksson
Not sure why it was disabled for 32bit in the first place?
2014-01-10erts: Extend binary_SUITE:ttb_trap to also cover binary_to_termSverker Eriksson
and rename it 'trapping'.
2014-01-10erts: Remove the extra_root feature from the process structureSverker Eriksson
as we don't use it and instead have the feature to disable GC during trapping BIFs.
2014-01-10erts: Simplify term_to_binary by removing saved ESTACK from root setSverker Eriksson
We disabled GC (in 522a29666088d5) during trapping and don't need to include the saved ESTACK as part of root set.

2014-01-07erts: Fix bs_get_integer instructionBjörn-Egil Dahlberg
The instruction bs_get_integer could unnecessarily trigger a garbage collection in failure cases which is unwanted or outright dangerous. Ex: <<X:Sz,_/bits>> = <<"some binary">> Previously, if Sz induced X to a bignum it would reserved memory size this on the heap via a garbage collection before checking if the size could actually match. It will now check the binary size before triggering a collection.
