The linker avoids a GOT indirection by turning a MOV into
a LEA, but with x86-64 GCC has started emitting CMOV*
instructions which break the existing logic.
This will generate errors such as:
unexpected GOT reloc for non-dynamic symbol luaO_nilobject_
The CMOV* instructions may be emitted with normal code like:
if (o >= L->top) return cast(TValue *, luaO_nilobject);
else return o;
Which gets compiled into (relocation offset at 1b):
13: 48 3b 47 10 cmp 0x10(%rdi),%rax
17: 48 0f 43 05 00 00 00 cmovae 0x0(%rip),%rax
1e: 00
This change will allow the indirection through the GOT to
avoid the problem in those cases.

It is unmaintained and untested, and I think it's broken too.
It was a toy to show that Go can run on real hardware,
and it served its purpose.
The source code will of course remain in the repository
history, so it could be brought back if needed later.

The implementation of the position computation
was surprisingly broken. Implemented fixes and
added extra test cases.
There is a slight interface change: Calling
Pos() returns the current position; but if
called before Scan() that position may not
be the position of the next token returned
by Scan() (depending on the scan settings
and the source text) - this in contrast to
the original comment.
However, after calling Scan(), the Scanner's
Position field reports the position of the
scanned token, as before.
Fixes#1327.

New ftplugin adds Import and Drop commands for Go buffers
in Vim. These commands ensure that the provided package is
imported (or not imported) in the current Go buffer, using
proper style and ordering, without moving the cursor.
E.g.
:Import strings
:ImportAs . strings
:Drop strings
Two mappings are also introduced to help with the fmt package:
\f => :Import fmt
\F => :Drop fmt

Init may report an error on the first character and
thus one needs an ability to set the error handler
for Init. Was a design bug.
Added corresponding test cases and better documentation.
Also: Fixed a subtle infinite loop exposed by one of the
new test cases.
Fixes#1380.

If a file pattern is given and matches files that look
like they need to be hg added or hg removed, offer to do so.
If a file pattern is given and matches files in another CL, warn.
If a file pattern doesn't match anything, point that out.

The test code used to do this:
for _, tc := range tests {
ch <- &tc
}
Note that &tc is always the same value here. As the value is
received from the channel, the sender can loop around and
change the contents of tc. This means that the receiver's
value is unstable and can change while it is in use.
