Rework eshell-match-result for testing asynchronous commands
When using eshell-match-result via eshell-command-result-p to examine

Don't output spurious prefixes in read-char-exclusive

This slows down some less used function call paths by a small amount
but the code duplication was just silly.
* src/bytecode.c (exec_byte_code): Inline aref and aset for
vectors and records, since this is important for code that makes heavy
use of arrays and/or objects.
It was implemented but never generated, originally intended for
TCO in the pre-lexbind era (which was semantically dubious anyway).
Removing it speeds up the interpreter because there is no longer any
need for the outermost `count` variable unless checking is enabled.

* src/bytecode.c (exec_byte_code): Perform bytecode unwinding error
check only when building with debugging (NDEBUG not defined, checking
enabled, or BYTE_CODE_SAFE enabled). This improves speed in several
ways.
Since we pass no arguments to a non-lexbind bytecode function, we can
specify its arity as 0 instead of nil and save a test and branch.

Change the args_template parameter type to ptrdiff_t, since it is now
always a small integer, in exec_byte_code and
fetch_and_exec_byte_code, all callers adjusted.
Avoid making a copy (in the interpreter C stack frame) of the bytecode
string by making sure it won't be moved by the GC. This is done by
reallocating it to the heap normally only used for large strings,
which isn't compacted.
This requires that we retain an explicit reference to the bytecode
string object (`bytestr`) lest it be GCed away should all other
references vanish during execution. We allocate an extra stack slot
for that, as we already do for the constant vector object.
