php-in-php: re-delete ParseStrUserScriptDelimitedJit — MultipartRuntime PHP makes #18548 LLVM restore obsolete (#1492)

Problem

#18548 restored ~1052-line ParseStrUserScriptDelimitedJit.php because StringMultipartStandaloneLlvm linked __phpc_parse_str_* subhelpers. #18615 deleted StringMultipartStandaloneLlvm and routes user-script multipart through MultipartNativeJitHelper + ParseStrNativeJitHelper PHP.

ParseStrRuntimeShrinkTest and SuperglobalRefreshRuntimeShrinkTest still expect the hand-LLVM file deleted; current master has 4 failing assertions.

Path	Registry	Delimited parse
User-script AOT (target)	ParseStrNativeJitHelper PHP	parseDelimitedIntoNative PHP
Current (regression)	ParseStrUserScriptDelimitedJit ~1052 LOC LLVM	__phpc_parse_str_parse_delimited_pairs etc.

php-src reference

• php/php-src ext/standard/basic_functions.c — PHP_FUNCTION(parse_str)

PHP implementation target

• Delete lib/JIT/Builtin/ParseStrUserScriptDelimitedJit.php
• lib/JIT/Builtin/ParseStrRuntime.php — drop ensureSubhelpers call; keep ParseStrNativeJitHelper bridge
• test/unit/JIT/SuperglobalsBracketRuntimeStandaloneTest.php — expect PHP bridges, not __phpc_parse_str_* LLVM
• test/selfhost/compiler_lib_spine_smoke/main.php — remove require

Repro

php vendor/bin/phpunit test/unit/ParseStrRuntimeShrinkTest.php
# 4 failures: file exists, spine includes require, ParseStrRuntime references class

Done when

• ParseStrUserScriptDelimitedJit.php deleted (~1052 LOC LLVM removed)
• ParseStrRuntimeShrinkTest + SuperglobalRefreshRuntimeShrinkTest green
• ./script/check-aot-build-smoke.sh green
• make bootstrap-selfhost-vm-driver-execute-probe green

claim: PHP Runtime → PHP — starting this run.

Merged via #18645.

LLVM shrink: deleted ParseStrUserScriptDelimitedJit.php (−1052 LOC). User-script AOT parse_str/multipart now routes exclusively through ParseStrNativeJitHelper + MultipartNativeJitHelper PHP bridges in ParseStrRuntime / MultipartRuntime.

Verification:

• ParseStrRuntimeShrinkTest — 13/13 OK (was 4 failures on master)
• SuperglobalRefreshRuntimeShrinkTest — OK
• SuperglobalsBracketRuntimeStandaloneTest — OK
• check-selfhost-spine-coverage-sync — OK
• bootstrap-selfhost-vm-driver-execute-probe — OK
