Tests updated to explicitly use fast-isel at -O0 instead of implicitly. This change also allows an explicit -fast-isel option to override an implicitly enabled global-isel. Otherwise -fast-isel would have no effect at -O0. Differential Revision: https://reviews.llvm.org/D41362 llvm-svn: 321655

; If the .tlsdesccall and blr parts are emitted completely separately (even with
|
|
; glue) then LLVM will separate them quite happily (with a spill at O0, hence
|
|
; the option). This is definitely wrong, so we make sure they are emitted
