Adds softfloat64 to generic runtime
(will be discarded by linker when unused)
and adds test for it.  I used the test to check
the software code against amd64 hardware
and then check the software code against
the arm and its simulation of hardware.
The latter should have been a no-op (testing
against itself) but turned up a bug in 5c causing
the vlrt.c routines to miscompile.

These changes make the cmath, math,
and strconv tests pass without any special
accommodations for arm.

There are other missing conversion cases
still but they do not show up in my tests.
This one is needed for vlrt.c's _v2d (int64, uint64 -> float).

Thankfully, VFP has a single instruction to do this.

Remove wasn't nil'ing the *Element.id. This property was exploited
by MoveToFront and MoveToBack internally, so I renamed the existing
Remove to "remove", and created an exported wrapper "Remove" that does
the right thing for the user's sake.

Also, saved an allocation by using *List as the id rather than *byte.

Simplify error handling during the compilation phase.

R=rsc

https://golang.org/cl/2652042

Remove err from the encoderState and decoderState types, so we're
not always copying to and from various copies of the error, and then
use panic/recover to eliminate lots of error checking.

another pass might take a crack at the same thing for the compilation phase.

Sub-symbols are laid out inside a larger symbol
but can be addressed directly.

Use to make Mach-O pointer array not a special case.

Will use later to describe ELF sections.

The implemetation describes each value as a string identifying the
concrete type of the value, followed by the usual encoding of that
value.  All types to be exchanged as contents of interface values
must be registered ahead of time with the new Register function.
Although this would not seem strictly necessary, the linker garbage
collects unused types so without some mechanism to guarantee
the type exists in the binary, there could be unpleasant surprises.
Moreover, the receiver needs a reflect.Type of the value to be
written in order to be able to save the data. A Register function
seems necessary.

The implementation may require defining types in the middle of
of sending a value.  The old code never did this. Therefore there
has been some refactoring to make the encoder and decoder
work recursively.

This change changes the internal type IDs. Existing gob archives
will break with this change.  Apologies for that. If this is a deal
breaker it should be possible to create a conversion tool.

Error handling is too complicated in this code. A subsequent
change should clean it up.

For elements which are themselves composite literals, the type may
be omitted if it is identical to the element type of the containing
composite literal.
