When the first call to Do finished, it calls c.wg.Done() to signal
others that the call was done. However, that happens without holding
a lock, so if others call to Do complete and be followed by a call to
ForgotUnshared, that then returns false.
Fixing this by moving c.wg.Done() inside the section guarded by g.mu, so
the two operations won't be interrupted.
Thanks bcmills@ for finding and suggesting fix.

A key may be forgotten while the call is still in flight. So when the
call finished, it should only delete the key if that key is associated
with the call. Otherwise, we may remove the wrong newly created call.

All inlined functions are Go functions, and thus should be capable of
having a FuncInfo. Missing FuncInfo is likely indication of a compiler
bug that dropped the symbol too early, failing to add it to the symbol
list used for writing output. I believe all existing cases have been
fixed; this check will prevent regressions.
The exception is -linkshared mode. There symbols are loaded from the
shared library, and the FuncInfo is not available. This is a bug, as it
can result in incorrect the FuncID in inlinedCall, but it is very
involved to fix.
For #54959.

The linker needs FuncInfo metadata for all inlined functions. This is
typically handled by gc.enqueueFunc calling ir.InitLSym for all function
declarations in typecheck.Target.Decls (ir.UseClosure adds all closures
to Decls).
However, non-trivial closures in Decls are ignored, and are insteaded
enqueued when walk of the calling function discovers them.
This presents a problem for direct calls to closures. Inlining will
replace the entire closure definition with its body, which hides the
closure from walk and thus suppresses symbol creation.
Explicitly create a symbol early in this edge case to ensure we keep
this metadata.
InitLSym needs to move out of ssagen to avoid a circular dependency (it
doesn't have anything to do with ssa anyway). There isn't a great place
for it, so I placed it in ir, which seemed least objectionable.
The added test triggers one of these inlined direct non-trivial closure
calls, though the test needs CL 429637 to fail, which adds a FuncInfo
assertion to the linker. Note that the test must use "run" instead of
"compile" since the assertion is in the linker, and "compiler" doesn't
run the linker.
Fixes#54959.

This change moves Linux epoll's syscalls implementation to the
"runtime/internal/syscall" package. The intention in this CL was to
minimise behavioural changes but make the code more generalised. This
also will allow adding new syscalls (like epoll_pwait2) without the
need to implement assembly stubs for each arch.
It also drops epoll_create as not all architectures provide this call.
epoll_create1 was added to the kernel in version 2.6.27 and Go requires
Linux kernel version 2.6.32 or later since Go 1.18. So it is safe to
always use epoll_create1.
