Summary:
lifetime2.C violates DR1696, which prevents reference members from being
initialized to temporaries, whose lifetime would end at the end of ctor.

Summary:
The waterfall no longer builds .s files and no longers uses
the wasm-o when it builds object files.

Add an explicit check before looking up symbol in SymbolIndices.
This was previously silently succeeding and returning zero for such
unnamed temporaries.

Summary:
Update GCC test suite failure expectations as we add -O0 to the bare tests in
WebAssembly waterfall. There are still several untriaged lld failures.

Undefined externals don't need to have a size or an offset.
This was broken by r303915. Added a test for this case.
This fixes the "Compile LLVM Torture (o)" step on the wasm
waterfall.

CopyToReg nodes don't support FrameIndex operands. Other targets select
the FI to some LEA-like instruction, but since we don't have that, we
need to insert some kind of instruction that can take an FI operand and
produces a value usable by CopyToReg (i.e. in a vreg). So insert a dummy
copy_local between Op and its FI operand. This results in a redundant
copy which we should optimize away later (maybe in the post-FI-lowering
peephole pass).

Instead of passing varargs directly on the user stack, allocate a buffer in
the caller's stack frame and pass a pointer to it. This simplifies the C
ABI (e.g. non-C callers of C functions do not need to use C's user stack if
they have their own mechanism) and allows further optimizations in the future
(e.g. fewer functions may need to use the stack).

Summary:
Just does the simple allocation of a stack object and passes
a pointer to the callee.

A recent change introduced this assertion failure in some corner cases.
Repro:

Many tests are now passing due to eliminateFrameIndex implementation and
the list needs to be re-triaged because it unblocks other failures, and
some previous failures are different. However I'm about to churn it more
by implementing more lowering, so will wait on that.

The bots are now running the torture tests properly. Bin all failures from the GCC C torture tests so that we can tackle failures and make the tree go red on regressions.
