Returns the mark-live pass to be used for this link.
If no pass is returned (the default) then the target-specific linker implementation will choose a conservative default (usually marking all symbols live). This function is only called if shouldAddDefaultTargetPasses returns true, otherwise the JITContext is responsible for adding a mark-live pass in modifyPassConfig.

Called by JITLink to resolve external symbols.
This method is passed a lookup continutation which it must call with a result to continue the linking process.

inlineoverridevirtual |
Called by JITLink to notify the context that the object has been finalized (i.e.
emitted to memory and memory permissions set). If all of this objects dependencies have also been finalized then the code is ready to run.

inlineoverridevirtual |
Called by JITLink once all defined symbols in the graph have been assigned their final memory locations in the target process.
At this point the LinkGraph can be inspected to build a symbol table, however the block content will not generally have been copied to the target location yet.
If the client detects an error in the LinkGraph state (e.g. unexpected or missing symbols) they may return an error here. The error will be propagated to notifyFailed and the linker will bail out.
