To support the efficient packing and extracting of sparse files,
add two new methods:
func Reader.WriteTo(io.Writer) (int64, error)
func Writer.ReadFrom(io.Reader) (int64, error)
If the current archive entry is sparse and the provided io.{Reader,Writer}
is also an io.Seeker, then use Seek to skip past the holes.
If the last region in a file entry is a hole, then we seek to 1 byte
before the EOF:
* for Reader.WriteTo to write a single byte
to ensure that the resulting filesize is correct.
* for Writer.ReadFrom to read a single byte
to verify that the input filesize is correct.
The downside of this approach is when the last region in the sparse file
is a hole. In the case of Reader.WriteTo, the 1-byte write will cause
the last fragment to have a single chunk allocated.
However, the goal of ReadFrom/WriteTo is *not* the ability to
exactly reproduce sparse files (in terms of the location of sparse holes),
but rather to provide an efficient way to create them.
File systems already impose their own restrictions on how the sparse file
will be created. Some filesystems (e.g., HFS+) don't support sparseness and
seeking forward simply causes the FS to write zeros. Other filesystems
have different chunk sizes, which will cause chunk allocations at boundaries
different from what was in the original sparse file. In either case,
it should not be a normal expectation of users that the location of holes
in sparse files exactly matches the source.
For users that really desire to have exact reproduction of sparse holes,
they can wrap os.File with their own io.WriteSeeker that discards the
final 1-byte write and uses File.Truncate to resize the file to the
correct size.
Other reasons we choose this approach over special-casing *os.File because:
* The Reader already has special-case logic for io.Seeker
* As much as possible, we want to decouple OS-specific logic from
Reader and Writer.
* This allows other abstractions over *os.File to also benefit from
the "skip past holes" logic.
* It is easier to test, since it is harder to mock an *os.File.

This change makes it easier to express instructions
with arbitrary number of operands.
Rationale: previous approach with operand "hiding" does
not scale well, AVX and especially AVX512 have many
instructions with 3+ operands.
x86 asm backend is updated to handle up to 6 explicit operands.
It also fixes issue with 4-th immediate operand type checks.
All `ytab` tables are updated accordingly.
Changes to non-x86 backends only include these patterns:
`p.From3 = X` => `p.SetFrom3(X)`
`p.From3.X = Y` => `p.GetFrom3().X = Y`
Over time, other backends can adapt Prog.RestArgs
and reduce the amount of workarounds.

Return early from deltimer, with false as the result,
to indicate that we couldn't delete the timer since its
timersBucket was nil(not set) in the first place.
That happens in such a case where a user created
the timer from a Ticker with:
t := time.Ticker{C: c}
The above usage skips the entire setup of assigning
the appropriate underlying runtimeTimer and timersBucket,
steps that are done for us by time.NewTicker.
CL 34784 introduced this bug with an optimization, by changing
stopTimer to retrieve the timersBucket from the timer itself
(which is unset with the mentioned usage pattern above),
whereas the old behavior relied on indexing
by goroutine ID into the global slice of runtime
timers, to retrieve the appropriate timersBucket.
