CodeCache should check that the UnlinkedCodeBlock was successfully created before caching it
https://bugs.webkit.org/show_bug.cgi?id=196880

Reviewed by Yusuke Suzuki.

JSTests:

* stress/bytecode-cache-syntax-error.js: Added.
(catch):

Source/JavaScriptCore:

CodeCache should not tell the SourceProvider to cache the bytecode if it failed
to create the UnlinkedCodeBlock.

* runtime/CodeCache.cpp:
(JSC::CodeCache::getUnlinkedGlobalCodeBlock):

Tools:

Add a new function for bytecode cache tests that does not forceDiskCache
for the second run: runBytecodeCacheNoAssetion. This is necessary for the
test added in this patch, since the code is invalid and therefore won't be
cached. It should also be useful for tests that evaluate dynamically
generated code.
