stage2 was adding bogus error return trace frames when an error was not
being returned. This commit makes several improvements:
* Make a runtime check if necessary to only emit a frame into the error
return trace when an actual error is returned.
* Use the `analyzeIsNonErrComptimeOnly` machinery to avoid runtime
checks when it is compile-time-known that the value is an error, or a
non-error.
* Make std.builtin.returnError take a non-optional stack trace pointer.

This new search placeholder looks much nicer because it allows HTML inside it which
the `placeholder` attribute on `<input>`s doesn't allow.
I tested it for all kinds of cases and it seems to work pretty well.
"Dialog" is the incorrect term here because a dialog is a separate window that still lets you use the app
but a modal is a window where you can't continue using the app until you close it.
- removed an unnecessary (and confusing) `anyerror` fronm the function
signature of `main`
- replaced the call to std.log with two prints: one to stderr and one to
stdout
- replaced the test code with a better example
Instead of generating sections upfront, allow generation by scanning
the object files for input -> output sections mapping. Next, always
strive to keep output sections in the final container sorted as they
appear in the final binary. This makes the linker less messy wrt
handling of output sections sort order for dyld/macOS not to complain.
There's still more work to be done for incremental context though
to make this work but looks promising already.
Previously we expected to only find decl refs in a `foo.bar.baz`
type of expression. This would crash when trying to render something
like `@typeInfo(T).Int.bits`. We now properly account for builtins
and other components.

Now instead of zig.h being baked into the compiler binary, it is a
header file distributed along with all the other header files
distributed with Zig.
