Dan Gohman 77502c9344 Enhance address-mode folding of ISD::ADD to handle cases where the
operands can't both be fully folded at the same time. For example,
in the included testcase, a global variable is being added with
an add of two values. The global variable wants RIP-relative
addressing, so it can't share the address with another base
register, but it's still possible to fold the initial add.
