When using `-Xclang -dump-tokens`, the lexer dump output is currently
difficult to read because the data are misaligned. The existing
implementation simply separates the token name, spelling, flags, and
location using `'\t'`, which results in inconsistent spacing.
For example, the current output looks like this on provided in this
patch example **(BEFORE THIS PR)**:

/>
# Changes
This small PR improves the readability of the token dump by:
+ Adding padding after the token name and after the spelling (the
padding amount was chosen empirically to produce good average
alignment).
+ Swapping the order of location and flags (since flags can take up a
lot of space and disrupt alignment).
The result is a more readable output **(AFTER THIS PR)**:
<img width="1470" height="315" alt="image"
