Optimize reads of field projections of ByValPairs. This helps in the case of field projections of the results of checked binary operations. E.g.: _1 = CheckedAdd(const 1i32, const 2i32); assert(!(_1.1: bool), "attempt to add with overflow" -> bb1 Previously, the `_1.1` field projection lvalue would force_allocate `_1` so it could read the memory in the old-style way. Now checked math with its assertions will not allocate at all. The oom2.rs compile-fail test had to be re-written, because the old version of it no longer allocates _at all_ (yay!), so it would hit the stack depth limit instead, from recursion. 2016-10-16 20:58:22 -05:00			`#![feature(box_syntax, custom_attribute, attr_literals)]`
test suite now also passes on MIR-libstd Also enable some tests that were disabled for no apparant reason. (The comment in zst.rs was wrong, the test was disabled also for miri execution.) Delete env_args test as the args can actually be queried with MIR-libstd (currently, they are always empty) 2017-05-26 22:27:39 -05:00			`#![miri(memory_size=2048)]`
