Forcing the synchronization of 500 lines is both slower and
less precise than searching for a known sync point.
Unfortunately, though, the way to synchronize correctly is
using the grouphere instruction, which has a bug.
I've already proposed the fix to Vim, so future releases
should have this working. We can continue using the 500 lines
syncing for now.
This change just documents the proper way to sync.

If there were warnings or errors in the user code,
cgo would print the first error from gcc and then stop,
which is not helpful.
This CL makes cgo ignore errors from user code
in the first pass - they will be shown later.
It also prints errors from user preamble code
with the correct line numbers.
(Also fixed misleading usage message).

The "all:" target is the default for running gomake
by hand, but it is not used during the build.
The build runs make install and make test.
Save the build of maketables for the test phase
so that the packages it needs will have been
installed already.

The sanity checking in pass 2 is wrong
when a select is offering to communicate in
either direction on a channel and neither case
is immediately ready.

The old heap maps used a multilevel table, but that
was overkill: there are only 1M entries on a 32-bit
machine and we can arrange to use a dense address
range on a 64-bit machine.
The heap map is in bss. The assumption is that if
we don't touch the pages they won't be mapped in.
Also moved some duplicated memory allocation
code out of the OS-specific files.

- complex numbers now supported.
- entirely independent of standard decode code.
- parser has no read-ahead; that is, the scanning works
simply by reading the values as they arrive, not by trying
to count bytes for message boundaries, a proof of concept
for the pending rewrite of the regular decoder.

This bug prevented files such as READMEs etc. from being included in the index.
For instance, now author names recorded in the AUTHORS file can be found with
a godoc query.

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.
