Recognising tribble() / frame_data() calls and allign arguments

[lorenzwalthert]

These calls calls should be recognised and it's argument should be aligned (or alignment should be kept if already correct).

frame_data(
  ~subject,    ~time, ~age, ~weight, ~height,
  "John Smith",    1,   33,      90,    1.87,
  "Mary Smith",    1,   NA,      NA,    1.54
)

Reference: tidyverse/tidyr#392 (comment)

This functionality should preferably be implemented in a transformer and not hard-coded.
