Pavel Afremov updated HARMONY-4407:
-----------------------------------

    Attachment: 0001-Fix-SOE-support-on-Windows-x86-64.patch

Fix SOE support on Windows x86-64.

On Windows x86-64.DRL VM can't process SOE, because one page on the stack is not enough to create exception.
But on Windows x86-64 there is function SetThreadStackGuarantee, which allow increase size of guard stack.
Unfortunately this function doesn't work on Windows x86-32 now. 
Current patch enable use of this function on x86-64 platform.
Also it fix asm_helpers for exception callback functions, compile_me function checks, and si_set_callback.
