Add dynamic-array unique() and unique_index() support and extend queue/darray min() and max() to accept locator with(...) predicates. Generate dedicated _with sfuns for min/max, emit VVP code for filtered scans, and reduce through new object-stack min/max opcodes.
Cover the new behavior with ivtest regressions for darray unique and queue/darray min/max with predicates, and update locator method documentation.

Implement queue and dynamic-array min()/max() for integral vec4 element types, with VVP support for both queue-backed and darray-backed storage and regressions in ivtest. Keep min/max as no-arg methods and document current behavior alongside existing locator tests.

Implement array locator methods for SystemVerilog queues and dynamic arrays:
find, find_index, find_first, find_first_index, find_last, find_last_index,
unique, and unique_index. Support both value arguments (equality) and
with (predicate) forms using implicit item and index in the iterator scope.
Elaboration returns queue-typed results for first/last/index locators per LRM
(empty queue when no match). Fix assignment compatibility between queues and
dynamic arrays where element types match.
VVP: extend %queue/size, %queue/word, %queue/find*, and %queue/unique* paths
so nets holding vvp_darray (including atom-backed int[]) are handled, not
only vvp_queue_vec4. Queue types still subclass vvp_darray; resolve vec4
queues before plain dynamic arrays. Fall back to the legacy get_queue_object
path for non-vec4 queues. Document opcode and source file touchpoints in
ivtest/ivltests/README_sv_queue_locators.txt.
Add vvp regressions: sv_queue_find*, sv_queue_unique, sv_queue_find_locators_ext,
sv_darray_find_locators.

Implement call_chain_expr in the parser, PECallFunction chain prefixes,
elaboration for class methods on returned handles, and prefix class resolution
for width checks on multi-hop chains. Place call_chain_expr before bare
hierarchy_identifier in expr_primary so id ( is not reduced as a lone ident.
Document behavior and developer notes in devel/sv_call_chain.md (including
that iverilog uses the installed lib/ivl/ivl binary).
Add ivtest sv_call_chain_method1 normal test with -g2012.

Add vvp regression for push_front, push_back, pop_front, pop_back on
queue-typed class fields. Catches vvp opcode_table sort regressions that
surface as Invalid opcode at runtime.

This version works with the native Windows (mingw64 and clang64)
versions of Perl in MSYS2.
Note that warnings are disabled in the Environment.pm module because
Perl fails to notice that OLDOUT and OLDERR are used when restoring
the STDOUT and STDERR file handles.
When redirection operators are included in a command string passed to
the system() subroutine, it spawns an intermediate shell to handle the
redirection. This is particularly inefficient when running the tests
in MSYS2. Creating our own version of system() based on fork() and
exec() allows us to handle the redirection directly.
