Benedikt Meurer a50baa246e [turbofan] Reduce DataView access code duplication. 
Part of https://chromium-review.googlesource.com/1231994 that landed
earlier, but was reverted due to breakage. Landing this cleanup
separately instead.

Drive-by-fix: Also add test coverage for the cases that weren't covered
properly (according to the test coverage bot).
