- Cherry picked #10662 and fixed merge conflicts.
- Manualy merged the change from #11904.
- Did not merge #12236 since I'm not sure whether the issue
affects Godot 2.1 and I don't have VS2013 to test.
- Did not merge #11843 since it doesn't seem relevant (the
code is only needed for creating DONORS.md, etc.).
- Did not merge #10727 and #11752 since they seem to be
already included in #11742.
- The Windows and Linux builds have been tested with Scons 3.0
using Python 3.
- OSX and iOS should hopefully work but are not tested since
I don't have a Mac.
- Builds using SCons 2.5 and Python 2 should not be impacted.
This backports the work in #7815 and the subsequent fixes in #8393
The following program now works as expected in this branch in both
release_debug and debug mode:
```gdscript
print(sqrt(-1))
print(sqrt(-1))
var simple1=asin(10.0)
var simple2=acos(10.0)
print(simple1)
print(simple2)
```
And successfully prints -nan 4 times
This fixes#9580 and fixes#8925
