auto merge of #9677 : thestinger/rust/immediate, r=huonw
C-like enums are excluded from this for now, because the code paths
specific to them need to be changed.
fn foo() -> Option<~int> { Some(~5) }
Before:
; Function Attrs: uwtable
define void @_ZN3foo18hdec6e36682b87eeaf4v0.0E(%"enum.std::option::Option<~int>[#1]"* noalias nocapture sret, { i64, %tydesc*, i8*, i8*, i8 }* nocapture readnone) #0 {

%3 = bitcast %"enum.std::libc::types::common::c95::c_void[#1]"* %2 to i64*

store i64* %3, i64** %4, align 8
ret void
}
After:
; Function Attrs: uwtable

%oldret = insertvalue %"enum.std::option::Option<~int>[#1]" undef, i64* %2, 0
