This essentially drops the change by r288021 (discussed with Georgii Rymar and Peter Smith and noted down in the release note of lld 10). GNU ld>=2.31 enables -z separate-code by default for Linux x86. By default (in the absence of a PHDRS command) a readonly PT_LOAD is created, which is different from its traditional behavior. Not emulating GNU ld's traditional behavior is good for us because it improves code consistency (we create a readonly PT_LOAD in the absence of a SECTIONS command). Users can add --no-rosegment to restore the previous behavior (combined readonly and read-executable sections in a single RX PT_LOAD).
