Load the entire archive file instead.
Reduces I/O by avoiding additional passes
through libraries to resolve symbols.
Go packages always need all the files anyway
(most often, all 1 of them).

Giving them specific types has the benefit that
binary.BigEndian.Uint32(b) is now a direct call, not an
indirect via a mutable interface value, so it can potentially
be inlined.

Recent changes to the spec relaxed the rules for comparison,
so this code is still valid:

	func isLittle(o binary.ByteOrder) { return o == binary.LittleEndian }

The change does break this potential idiom:

	o := binary.BigEndian
	if foo {
		o = binary.LittleEndian
	}

That must rewrite to give o an explicit binary.ByteOrder type.
On balance I think the benefit from the direct call and inlining
outweigh the cost of breaking that idiom.

Just enough to make mov instructions work,
which in turn is enough to make strconv work
when it avoids any floating point calculations.
That makes a bunch of other packages pass
their tests.

Should suffice until hardware floating point
is available.

Enable package tests that now pass
(some due to earlier fixes).

Looks like there is a new integer math bug
exposed in the fmt and json tests.

The frame that gets allocated is for both
the args and the autos.  If together they
exceed the default frame size, we need to
tell morestack about both so that it allocates
a large enough frame.

Sanity check stack pointer in morestack
to catch similar bugs.

That is, move the pc/ln table and the symbol table
into the read-only data segment.  This eliminates
the need for a special load command to map the
symbol table into memory, which makes the
information available on systems that couldn't handle
the magic load to 0x99000000, like NaCl and ARM QEMU
and Linux without config_highmem=y.  It also
eliminates an #ifdef and some clumsy code to
find the symbol table on Windows.

The bad news is that the binary appears to be bigger
than it used to be.  This is not actually the case, though:
the same amount of data is being mapped into memory
as before, and the tables are still read-only, so they're
still shared across multiple instances of the binary as
they were before.  The difference is just that the tables
aren't squirreled away in some section that "size" doesn't
know to look at.

This is a checkpoint.
It probably breaks Windows and breaks NaCl more
than it used to be broken, but those will be fixed.
The logic involving -s needs to be revisited too.
