Not sure why we switched from homebrew to scons-local anymore,
but pip should work just fine and is recommended by upstream.
Downloads of scons-local from SourceForge were quite iffy, so
this should help avoid CI errors due to not having downloaded
SCons successfully.
Setting Python's user binary PATH seems necessary on Travis/OSX
as per travis-ci/travis-ci#5030 (confirmed that 'scons' is not
in PATH without it).
Godot supports many different compilers and for production releases we
have to support 3 currently: GCC8, Clang6, and MSVC2017. These compilers
all do slightly different things with -ffast-math and it is causing
issues now. See #24841, #24540, #10758, #10070. And probably other
complaints about physics differences between release and release_debug
builds.
I've done some performance comparisons on Linux x86_64. All tests are
ran 20 times.

I have also looked at FPS numbers for tps-demo, 3d platformer, 2d
platformer, and sponza and could not find any measurable difference.
I believe that given the issues and oft-reported (physics) glitches on
release builds I believe that the couple of percent of tight-loop
floating point performance regression is well worth it.
This fixes#24540 and fixes#24841
This fixes the previously wrong PR
Because we don't actually ship 'debug' templates to users make sure
the mono exporter picks the correct 'data' directory for export
templates.

Background: lstrip and rstrip were broken by changes to String in:
0e29f7974b
which removed it's access to Vector::find(CharType).
Moved Vector's find up into CowData so it can be shared by Vector and String.
Added String::find_char using CowData::find.
Implemented rstrip and lstrip using find_char.
Added a few tests for String rstrip and lstrip.
