sema: analyze field init bodies in a second pass
...
This change allows struct field inits to use layout information
of their own struct without causing a circular dependency.
`semaStructFields` caches the ranges of the init bodies in the `StructType`
trailing data. The init bodies are then resolved by `resolveStructFieldInits`,
which is called before the inits are actually required.
Within the init bodies, the struct decl's instruction is repurposed to refer
to the field type itself. This is to allow us to easily rebuild the inst_map
mapping required for the init body instructions to refer to the field type.
Thanks to @mlugg for the guidance on this one!

frontend: fix -fsingle-threaded default detection logic
...
The logic in 509be7cf1f10c5d329d2b0524f2af6bfcabd52de assumed that
`use_llvm` meant that the LLVM backend would be used, however, use_llvm
is false when there are no zig files to compile, which is the case for
zig cc. This logic resulted in `-fsingle-threaded` which made libc++
fail to compile for C++ code that includes the threading abstractions
(such as LLVM).

io_uring: add multishot accept operation
...
Server networking application typically accept multiple connections. Multishot
accept simplifies handling these situations. Applications submits once and
receives CQE whenever a new connection request comes in.
Multishot is active until it is canceled or experience error. While active, and
further notification are expected CQE completion will have IORING_CQE_F_MORE set
in the flags. If this flag isn't set, the application must re-arm this request
by submitting a new one.
