[Bf-committers] OSL / LLVM / Freetype library updates.

[Ray Molenkamp]

Fellow Platform devs,

Due to various issues in several of the dependencies some of them
have been bumped to new versions.

OSL 1.10.9 / LLVM 9.0.1 - D6744
FreeType 2.10.1 - D6645

Please update these libraries for *Master only*, 2.82 will ship
with the old versions!

You may see SVN commits from me for other dependencies (oidn, libxml)
these are just windows build fixes in the current versions, no versions
are changed, no action is required for the linux/mac platforms.

Greetings,
Ray
