-----------
HeapSnapshotBuilder should support printing directly to a PrintStream
https://bugs.webkit.org/show_bug.cgi?id=302397
rdar://164555302
Reviewed by Mark Lam.
Adds support for writing directly to a file descriptor (or I guess os_log
but good luck) via PrintStream. This is helpful when trying to understand
the heap near a jetsam limit on iOS.
Also, fixes a longstanding issue where character literals would print
as a integral rather than ASCII. Since `char`, `signed char`, and
`unsigned char` are all different types in C++, I think adding an
extra overload for `char` should "just work" as it's poor style to use
something other than `int8_t`/`uint8_t` for one byte integral values
in WebKit at this point.
