Use LLVM 10.0.0 on darwin omnibus builds (#97)

* Build llvm 10.0.1

* Bump osx build environment to xcode: 11.1.0

* Allow libRemarks.dylib

          [HealthCheck] E | 2020-08-06T17:33:43-03:00 | The following binaries have unsafe or unmet dependencies:
    --> /opt/llvm//lib/libRemarks.dylib

            [HealthCheck] E | 2020-08-06T17:33:43-03:00 | The following libraries cannot be guaranteed to be on target systems:
    --> @rpath/libRemarks.dylib

            [HealthCheck] E | 2020-08-06T17:33:43-03:00 | The precise failures were:
    --> /opt/llvm//lib/libRemarks.dylib
    DEPENDS ON: libRemarks.dylib
      COUNT: 1
      PROVIDED BY: @rpath/libRemarks.dylib
      FAILED BECAUSE: Unsafe dependency

* Build llvm 10.0.0

* Build llvm 6.0.1 with xcode 11.1.0

* Rebuild llvm 10.0.0

* Add llvm_bin for 10.0.0 darwin

* Use llvm 10.0.0 by default in omnibus

* Drop LLVM 10.0.1 sources since darwin has issues related to libxml2.tdb

* Upload libyaml source to S3

pyyaml.org seems to be restricting the user agent or at least the request from our CI
