Usually, an operation class has only one possible value of "info" word.
In this case, just compare the entire info word, do not bother
to mask OPCLSMASK bits.
(Example where this is not the case: OC_REPLACE for "<op>=")

Rework of the previous fix:
Can use operation attributes to disable arg evaluation instead of special-casing.

ptest() was using this idea already.
As far as I can see, this is safe. Ttestsuite passes.
One downside is that a temporary from e.g. printf invocation
won't be freed until the next printf call.

It seems to be designed to reduce overhead of malloc's auxiliary data,
by allocating at least 64 variables as a block.
With "struct var" being about 20-32 bytes long (32/64 bits),
malloc overhead for one temporary indeed is high, ~33% more memory used
than needed.

hash_find(): do not caclculate hash twice. Do not divide - can use
cheap multiply-by-8 shift.
nextword(): do not repeatedly increment in-memory value, do it in register,
then store final result.

We can free them after they are no longer needed.
(Currently, being a NOEXEC applet is much larger waste of memory
for the case of long-running awk script).

The same stored search pattern applies to both search ('/') and
search/replace (':s') operations.
A search/replace operation with an empty "find" string (':s//abc/')
should use the last stored search pattern, if available, and issue an
error message if there is none.
If the "find" string is not empty it should replace the stored search
pattern.
