mark character finding as pure. at some point we should do that systematically
about string functions.

this is on the silly side, but it helps the jit

two more unroll-safe needed

23722. By arigo on 2010-01-26

Add the jit.unroll_safe_if_const_arg decorator
to "x in (tuple)" and to string formatting.
Unsure if it's really a good idea in general
in string formatting, we will try.

Implement call_if_not_const in pyjitpl. Should be all.

23720. By arigo on 2010-01-26

Write the decorator, unroll_safe_if_const_arg(argpos).
Support it in codewriter.py.

23719. By arigo on 2010-01-26

Create a branch to implement rlib.jit.unroll_safe_if_const_arg().

23718. By arigo on 2010-01-26

Revert checkin by mistake.

Merge the branch/lazy-operr-format, replacing most

    raise OperationError(space.w_XxxError,
                         space.wrap("foo %s" % x))

with

    raise operationerrfmt(space.w_XxxError, "foo %s", x)

which is both a bit shorter and quite faster to run in the common case
where the exception is swallowed without being ever printed: the string
formatting is then never done.

Merge the direct-assembler-call branch.

This branch implements a new operation CALL_ASSEMBLER, which happens
when we encounter a recursive portal call to a place that has assembler
already compiled. Speeds up certain cases, some by a significant %.
Slows down megamorphic calls, because with this branch, a call that was
compiled as CALL_ASSEMBLER is now a guard failure in case code object
is not the same.
