Subject: Re-reapply "[IR] Move optional data in llvm::Function into a hungoff uselist"
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=ef112d46b98642b59c657f1560f7e1c21b13a0da;hp=ef112d46b98642b59c657f1560f7e1c21b13a0da;ds=sidebyside

Re-reapply "[IR] Move optional data in llvm::Function into a hungoff uselist"

Make personality functions, prefix data, and prologue data hungoff
operands of Function.

This is based on the email thread "[RFC] Clean up the way we store
optional Function data" on llvm-dev.

Thanks to sanjoyd, majnemer, rnk, loladiro, and dexonsmith for feedback!

Includes a fix to scrub value subclass data in dropAllReferences. Does not
use binary literals.
