Running JIT code under MSAN is (still) not officially supported, as it can (and does) give false positives; that said, this PR reduces the false positives in some cases. Specifically: (1) if we are building a JIT shared runtime (ie, we are jitting), and we are compiling with MSAN enabled (detected via preprocessor), we should always use the real MSAN stubs, even if the Target::MSan feature has been cleared (because JITModule::make_module() clears it). (2) Target::get_jit_from_environment() should add any detected sanitizer bits to the target sniffed from HL_JIT_TARGET
