It was off in the old implementation (because there was no high-level
description of the function at all). Maybe some day the race detector
should be fixed to handle the wrapper and then enabled for it, but there's
no reason that has to be today.

There's no reason to use a different name on each architecture,
and doing so makes it impossible for portable code to refer to
the original Go runtime entry point. Rename it _rt0_go everywhere.

This is a global search and replace only.

This feature is not yet ready for real use. The CL marks a bite-sized
piece that is ready for review. TODOs that remain:
        provide control over output
        produce output without setting -v
        make work on reflect, sync and time packages
                (fail now due to link errors caused by inlining)
        better documentation
Almost all packages work now, though, if clumsily; try:
        go test -v -cover=count encoding/binary

Requires adding new linker instruction
        RET	f(SB)
meaning return but then immediately call f.
This is what you'd use to implement a tail call after
fiddling with the arguments, but the compiler only
uses it in genwrapper.

This CL eliminates the copy-and-paste genembedtramp
functions from 5g/8g/6g and makes the code run on ARM
for the first time. It removes a small special case for function
generation, which should help Carl a bit, but at the same time
it does not bother to implement general tail call optimization,
which we do not want anyway.

The first identifier in an Object Identifer must be between 0 and 2
inclusive. The range of values that the second one can take depends
on the value of the first one.
The two first identifiers are not necessarily encoded in a single octet,
but in a varint.
