Performance and style fixes (#1981)
* Switch to integer ranges in for loops

Signed-off-by: Stephen Kitt <steve@sk2.org>

* Switch to slices functions where appropriate

A number of utility functions can be replaced outright; since Miller
can technically be used as a library, these are deprecated rather than
removed. go:fix directives ensure that they can be replaced
automatically.

Signed-off-by: Stephen Kitt <steve@sk2.org>

* Switch to reflect.TypeFor

This is slightly more efficient than TypeOf when the type is known at
compile time.

Signed-off-by: Stephen Kitt <steve@sk2.org>

* Switch to strings.SplitSeq instead of strings.Split

SplitSeq results in fewer allocations.

* Drop obsolete build directives

Signed-off-by: Stephen Kitt <steve@sk2.org>

* Use min/max instead of explicit comparisons

Signed-off-by: Stephen Kitt <steve@sk2.org>

* Append slices instead of looping
