* floating point -> integer conversions.
x86 defines that overflow/underflow
results in 1<<15, 1<<31, 1<<63 for
int16, int32, int64. when building the
unsigned conversions out of the native signed
ones, 8g turns overflow/underflow into zero.
the spec does not say what should happen.
* many tiny bug fixes. can run a large number
of files from go/test now, and can fmt.Printf.
* struggling with byte register allocation
and float32 computation.

avoid tight coupling between deferreturn and jmpdefer.
before, jmpdefer knew the exact frame size of deferreturn
in order to pop it off the stack. now, deferreturn passes
jmpdefer a pointer to the frame above it explicitly.
that avoids a magic constant and should be less fragile.

- Extend http.URLUnescape to convert '+' to space
- Add http.URLEscape
- Rename URL.Query to EncodedQuery (and stop decoding it, as decoding this field
before separating key/value pairs loses important information)
- Report a clean error on incomplete hex escapes
- Update existing tests, add new ones

auto-generated files and deletions are in another CL.
goals for new syscall:
* automate as much as possible
* do not let clients do unsafe things
* use simple types (int not int64)
* fewer files
the files are renamed from foo_amd64_linux to foo_linux_amd64,
both because it reads better (all the linux are related, all the amd64 less so)
and because it made it easier to replace the existing ones.

The change to assign.go is because the gcc testsuite fails to
handle .* in a normal way: it matches against the entire
compiler output, not just a single line.

The code was already careful not to use malloc/free
for stack growth during calls to malloc.
Avoid them during calls to free too.

* conversions all in one place.
* no separate load, store phases;
direct memory addressing when possible
(this is the x86 after all!).
avoids extra registers, extra MOVQs.
* fixes int32 -> uint64 bug
