Misleading text around JSC JIT/GC

[jrtc27]

In "Security analysis of CHERI ISA.pdf", section "Case study examples: CheriBSD and JSC" says:

It’s worth noting that qtwebkit and JSC do not support JIT or garbage collection

Whilst the table goes on to clarify somewhat (although not as clearly as it could) that this is a MIPS-specific restriction (more accurately MIPS64-specific, as there is a 32-bit JIT implementation), the main body should be clear about this too otherwise it will mislead. AArch64 does have a JIT implementation, although a Morello JIT would still need to be developed.
