  [ARM] Allow codegen for Armv6m eXecute-Only (XO) sections

This patch moves the overall lower-bound arch restriction for Arm XO sections
from v8m to v6m. Actual implementation of code-gen for v6m will follow in
follow-up patches, which will include an implementation of relocations needed to
support this.
