as the stdin for builtin_source

cab115c8b9 Don't stop job execution on wildcard errors
Wildcard errors are only reported interactively, and they're also not
really errors. Commands with multiple wildcards would in fact continue
executing if at least one wildcard matched, which is quite surprising.
But they would report an error if there is only one wildcard in the
arguments list and the wildcard has no match, even if there are other
remaining arguments.

Given this inconsistency, and given that sh does not stop execution if a
wildcard fails to match, it seems better to allow execution to continue.
This is better from a scripting perspective anyway, as it means
constructs like `set -l paths foo/*.txt` will actually create the
variable (with an empty value) instead of skipping the `set`
altogether and perhaps causing subsequent code to read or modify a
global or universal variable.

4568359e27 Remove some obsolete job flags
These flags were used by the old parser, but not by the new one.

07e4170418 Suppress wildcard errors in functions
Wildcard errors are only supposed to reported when encountered during
interactive use. The old parser also suppressed them if `is_block` was
true. This was lost in the new parser. However, this also suppresses
errors generated from `begin; code_here; end` and other block
constructs.

Instead, check the parser block stack when we hit an error, and suppress
the error if there are any function calls / events / source invocations.
These all indicate that the code being executed came from somewhere
other than the commandline.

0372cdbe7e Standardize unmatched wildcard errors
Unmatched wildcard errors during parsing are normally only reported when
run interactively. The switch command was unconditionally reporting them
anyway (and not setting the status to 124). Fix it so switch goes
through the same code path as everything else.

1fbf633817 Reimplement exec parsing. Instead of special-casing exec as a command,
