BaseTools CLANG35: drop problematic use-movt and save-temps options

BaseTools CLANG35: drop problematic use-movt and save-temps options

Some versions of Clang fail on every input file when using the
-save-temps options, and produces the following heplful error message:

  <unknown>:0: error: Undefined temporary symbol

Simply dropping the option for CLANG35 is the simplest way around this,
since the value of storing .i and .s files is dubious anyway.

Also, drop the arm-use-movt option, which does not appear to be
supported anymore by recent versions of clang.
