Some of the benchmarks we're using for PGO require unstable features (such as compiling the standard library and some rustc-perf benchmarks), breaking CI on the beta and stable branches. For the past two releases we cherry-picked a commit directly onto the beta branch that unconditionally sets
RUSTC_BOOTSTRAP=1, and this PR backports a similar change to the master branch.The difference between this commit and the one we backported previously (483c1a8) is that this is more scoped in which benchmarks we allow unstable features, to prevent unintentionally enabling unstable features.
