[Bug target/88402] inefficient code generation for mask from CC

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88402 --- Comment #3 from Alexander Monakov --- However, this may be worthwhile when one of operands is an immediate, as in that case there's no register pressure increase, and the xor just mutates the immediate. Essentially, we'd change e.g.

[Bug target/67288] [7/8/9 regression] non optimal simple function (useless additional shift/remove/shift/add)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67288 --- Comment #16 from Segher Boessenkool --- Many things in combine assume that they can move an earlier insn to later, if none of the registers it uses is set in the intermediate insns (etc.) This isn't correct if you make combine work on EBBs.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77499 --- Comment #17 from Jeffrey A. Law --- So if one manually does the sinking I suggest in c#14, we get the key insns into their own block (it's not *that* convoluted). That's still not enough to address the regression in this BZ. We lose the
