Rename a few scripts to be more consistent.

I'm also starting to feel the urge to bud off `subx run` into its own program,
say tools/emulate_x86. It doesn't really rely on the SubX notation at all.

And then I could rename `subx translate` to `translate_subx_bootstrap`.

Only problem: the commands in the Readme get verbose. But the Readme is
gonna need surgery soon anyway to put translate_mu front and center.

+#!/bin/sh
+# Translate SubX files with debug information on Linux.
+#
+# Mu's core tooling has a gap:
+#   0. The C++ translator 'subx translate' can generate debug information on
+#   Linux or BSD or Mac, but doesn't support any syntax sugar.
+#   1. The self-hosted translator 'translate' runs in emulated mode and can
+#   run on Linux or BSD or Mac. However, syntax sugar passes (sigils and
+#   calls) can be very slow to run emulated.
+#   2. The self-hosted translator 'translate_subx' runs natively on Linux. It is
+#   fast, but you get no trace for runs and zero error-checking on the code
+#   emitted by sigils and calls. Which could still be buggy.
+#
+# This script is a hack to get the best of all worlds. We run natively what we
+# must, and leverage as much debug information as possible. This arrangement
+# is snappy but requires Linux just like 'translate_subx'. You also are on your
+# own to mentally map desugared instructions in traces and error messages back
+# to the original sources.
