[PlayStation] JSC Stress tests failing due to timezone printing
https://bugs.webkit.org/show_bug.cgi?id=197615
PlayStation's strftime does not give timezone strings, which
results in time strings like "Wed Oct 23 1974 11:45:01 GMT-0700"
rather than "Wed Oct 23 1974 11:45:01 GMT-0700 (Pacific Daylight Time)"
which causes diff failures with the expectations. Add expectations

[JSC] imports-oom.js intermittently fails
https://bugs.webkit.org/show_bug.cgi?id=196373
Reviewed by Saam Barati.
imports-oom.js ensures that a wasm module compilation / instantiation throws an OOM error instead of crashing when compiling / instantiating their entry points
with extremely low executable memory amount. And this test expects we at least once successfully compile, instantiate, and execute a wasm module to test that
wasm implementation is always throwing an OOM error. However, maybe due to wasm changes, the amount of executable memory consumed by wasm compilation is changed,
and now we may encounter an OOM error at the first compilation. Since imports-oom.js randomize the amount of executable memory used by the generated wasm module,
imports-oom.js intermittently fails when it first generates large wasm module which cannot be compiled.
This patch reduces the maxParams from 32 to 8 to reduce the size of randomly generated wasm module. Since we repeatedly generate wasm modules, this test soon encounter
an expected OOM error. But this avoids the situation that we get an OOM error when we compile a first wasm module.

REGRESSION: stress/regress-178386.js is timing out on JSC debug bot
https://bugs.webkit.org/show_bug.cgi?id=194677
<rdar://problem/48112492>
Reviewed by Mark Lam.
Before r241233, String.fromCharCode (except for an empty string) always returns 16bit string.
This makes the rope generated by padEnd 16bit. When we resolve the rope inside JSON.stringify,
it immediately fails due the large size.
After r241233, String.fromCharCode starts returning 8bit string if possible. So the rope becomes
8bit, and we successfully resolve the rope in this case. Resolving such a large rope takes long
time and that is why stress/regress-178386.js starts timing out. Note that, the test fails with
OOM error anyway because JSON.stringify's builder overflows with such a large string input.
This patch changes the test to produce 16bit string from String.fromCharCode.

This test is super flaky. It causes crash in r238109, but it does not crash with `--useConcurrentJIT=false`.
It does not cause any crashes on the latest revision too. Basically, it highly depends on the timing, and
without this patch, the root cause is not fixed yet. If GetLocal is turned into JSConstant in AI,
but GetByVal does not have appropriate ArrayModes, JSC crashes.
