Tell _frozen_importlib to consider bytecode first (#248)

It turns out we needed a file length field.

+# Contributing Guidelines
+
+We'd love to accept your patches! Please read this guide first.
+
+## Copyright Assignment
+
+Please send an email to Justine Tunney <jtunney@gmail.com> stating that
+you intend to assign her the copyright to the changes you contribute to
+Cosmopolitan. Please use the same email address you use for git commits
+which should only contain original source code from you or other people
+who are also assigning copyright. Please note that, if you're employed,
+you may need to get your employer's approval beforehand. If you can not
+assign copyright due to local laws, then you may alternatively consider
+disclaiming it using the language in [Unlicense](https://unlicense.org)
+or [CC-0](http://creativecommons.org/share-your-work/public-domain/cc0)
+
+This is important because we can't produce 12kb single-file executables
+that comply with license requirements if we have to embed lots of them.
+Although that's less of an issue depending on the purpose of the files.
+For example, ownership is much less of a concern in the unit test files
+so you're encouraged to put your copyright on those, provided it's ISC.
+
+## Style Guide
+
+You can use clang-format to automatically format your files:
+
+```sh
+clang-format -i -style=file tool/net/redbean.c
+```
+
+If you use Emacs this can be automated on save for Cosmopolitan using
+[tool/emacs/cosmo-format.el]([tool/emacs/cosmo-format.el]).
+
+### Source Files
+
+- Must use include paths relative to the root of the repository
+- Must have comment at top of file documenting copyright and license
+- Must have notice embedding if not owned by Justine (exception: tests)
+- May use language extensions that are supported by both GCC and Clang
+- Should use Google indentation (otherwise use `/* clang-format off */`)
+- Should use asm() instead of compiler APIs (exception: ctz, clz, memcpy)
+
+### Header Files
+
+- Must not have copyright or license comments
+- Must have once guards (otherwise change `.h` to `.inc`)
+- Must be ANSI C89 compatible to be included in the amalgamation header
+- Must include its dependencies (exception: libc/integral/normalize.inc)
+- Must not define objects (i.e. `cc -c -xc foo.h` will produce empty `.o`)
+- Should not use typedefs
+- Should not use forward declarations
+- Should not include documentation comments
+- Should not include parameter names in prototypes
+- Should not pose problems if included by C++ or Assembly sources
+- Should not declare non-ANSI code, at all, when the user requests ANSI
+
+### Build Config
+
+- Must not write files outside `o/`
+- Must not communicate with Internet
+- Must not depend on system libraries
+- Must not depend on system commands (exception: sh, make, gzip, zip)

-Fast portable static native textmode executable containers.
+[Cosmopolitan Libc](https://justine.lol/cosmopolitan/index.html) makes C
+a build-once run-anywhere language, like Java, except it doesn't need an
+interpreter or virtual machine. Instead, it reconfigures stock GCC and
+Clang to output a POSIX-approved polyglot format that runs natively on
+Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS with the best
+possible performance and the tiniest footprint imaginable.

+## Background
+
+For an introduction to this project, please read the [αcτµαlly pδrταblε
+εxεcµταblε](https://justine.lol/ape.html) blog post and [cosmopolitan
+libc](https://justine.lol/cosmopolitan/index.html) website. We also have
+[API documentation](https://justine.lol/cosmopolitan/documentation.html).
+
+## Getting Started
+
+If you're doing your development work on Linux or BSD then you need just
+five files to get started. Here's what you do on Linux:
+
+```sh
+wget https://justine.lol/cosmopolitan/cosmopolitan-amalgamation-1.0.zip
+unzip cosmopolitan-amalgamation-1.0.zip
+printf 'main() { printf("hello world\\n"); }\n' >hello.c
+gcc -g -Os -static -nostdlib -nostdinc -fno-pie -no-pie -mno-red-zone \
+  -fno-omit-frame-pointer -pg -mnop-mcount \
+  -o hello.com.dbg hello.c -fuse-ld=bfd -Wl,-T,ape.lds \
+  -include cosmopolitan.h crt.o ape.o cosmopolitan.a
+objcopy -S -O binary hello.com.dbg hello.com
+```
+
+You now have a portable program. Please note that your APE binary will
+assimilate itself as a conventional resident of your platform after the
+first run, so it can be fast and efficient for subsequent executions.
+
+```sh
+./hello.com
+bash -c './hello.com'  # zsh/fish workaround (we upstreamed patches)
+```
+
+So if you intend to copy the binary to Windows or Mac then please do
+that before you run it, not after.
+
+### MacOS
+
+If you're developing on MacOS you can install the GNU compiler
+collection for x86_64-elf via homebrew:
+
+```sh
+brew install x86_64-elf-gcc
+```
+
+Then in the above scripts just replace `gcc` and `objcopy` with
+`x86_64-elf-gcc` and `x86_64-elf-objcopy` to compile your APE binary.
+
+### Windows
+
+If you're developing on Windows then you need to download an
+x86_64-pc-linux-gnu toolchain beforehand. See the [Compiling on
+Windows](https://justine.lol/cosmopolitan/windows-compiling.html)
+tutorial. It's needed because the ELF object format is what makes
+universal binaries possible.
+
+## Source Builds
+
+Cosmopolitan can be compiled from source on any Linux distro. GNU make
+needs to be installed beforehand. This is a freestanding hermetic
+repository that bootstraps using a vendored static gcc9 executable.
+No further dependencies are required.
+
+```sh
+wget https://justine.lol/cosmopolitan/cosmopolitan-1.0.tar.gz
+tar xf cosmopolitan-1.0.tar.gz  # see releases page
+cd cosmopolitan
+make -j16
+o//examples/hello.com
+find o -name \*.com | xargs ls -rShal | less
+```
