fourthTier: DFG IR dumps should be easier to read
https://bugs.webkit.org/show_bug.cgi?id=119050
Source/JavaScriptCore:
Reviewed by Mark Hahnenberg.
Added a DumpContext that includes support for printing an endnote
that describes all structures in full, while the main flow of the
dump just uses made-up names for the structures. This is helpful
since Structure::dump() may print a lot. The stuff it prints is
useful, but if it's all inline with the surrounding thing you're
dumping (often, a node in the DFG), then you get a ridiculously
long print-out. All classes that dump structures (including
Structure itself) now have dumpInContext() methods that use
inContext() for dumping anything that might transitively print a
structure. If Structure::dumpInContext() is called with a NULL
context, it just uses dump() like before. Hence you don't have to
know anything about DumpContext unless you want to.
inContext(*structure, context) dumps something like %B4:Array,
and the endnote will have something like:
%B4:Array = 0x10e91a180:[Array, {Edge:100, Normal:101, Line:102, NumPx:103, LastPx:104}, ArrayWithContiguous, Proto:0x10e99ffe0]
where B4 is the inferred name that StringHashDumpContext came up
with.
Also shortened a bunch of other dumps, removing information that
isn't so important.

Added support for dumping values within a context. By default, if you say
print(inContext(value, context)) it calls value.dumpInContext(out, context)
instead of value.dump(out).
Hoisted the support for six-character hashes out of JSC::CodeBlockHash into
WTF, in the form of SixCharacterHash.h.
Added a helper for creating dump contexts where the inContext() dump will
just use a short string hash to "name" the object being dumped, and then
will print out the full dumps in an endnote to your dump.
Added support for using CString as a hashtable key.
