Commit pushed to master at https://github.com/D-Programming-Language/dmd

https://github.com/D-Programming-Language/dmd/commit/0ccbc134da6c44b3ae922992d911d8a9dfdaa3c3
fix Issue 12197 - 'invalid array operation' errror message with valid array
operation

Make explicit importing std.math unnecessary for pow expressions.

Currently front-end does not enforce std.math module existence. Therefore,
there's not also necessity to explicitly import std.math in user code.
