This commit provides a "system_loader_es5.js" bundle loader which will be added
to the bundle when the target is < ES2017, which is the minimum target syntax
required for "system_loader.js".
Supports #5913 (via Deno.bundle()) with a couple caveats:
* Allowing "deno bundle" to take a different target is not supported, as we
specifically ignore "target" when passed in a TypeScript config file. This is
because deno bundle is really intended to generate bundles that work in Deno.
It is an unintentional side effect that some bundles are loadable in browsers.
* While a target of "es3" will be accepted, the module loader will still only be
compatible with ES5 or later. Realistically no one should be expecting bundles
generated by Deno to be used on IE8 and prior, and there is just too much
"baggage" to support that at this point.
This is a minor variation of 75bb9d, which exposed some sort of internal V8 bug.

This commit fixes several regressions in TS compiler:
* double compilation of same module during same process run
* compilation of JavaScript entry point with non-JS imports
* unexpected skip of emit during compilation
Additional checks were added to ensure "allowJs" setting is
used in TS compiler if JavaScript has non-JS dependencies.
This reverts commit c4c6a8dae4
There is some controversy about this change because vscode doesn't interpret the fragments correctly. Needs more discussion before landing.
Since everything that Deno loads is treated as an ES Module,
it means that all code is treated as "use strict" except for
when using the REPL. This PR changes that so code in the
REPL is also always evaluated with "use strict". There are
also a couple other places where we load code as scripts
which should also use "use strict" just in case.
