revert last commit. fails "make test"
...
test target in Makefile does not depend on tcc.
i'm not sure why, but i can think of at least one
good reason. in my local tree I have it modified
to do so, but somehow inadvertently reverted that
so when i did "make test" before committing, it
didn't actually test my changes. sorry.

clarify support for functions returning an array
...
previously, tcc would accept a prototype of a function returning
an array, but not giving those functions bodies nor calling them.
it seems that gcc has never supported them, so we should probably
just error out... but it's possible that someone already using
tcc includes some header that contains an unused prototype for
one, so let's continue to support that.

added a note clarifying post_type() recursion
...
some ancient pre-K&R C allows a function to return an array
and the array brackets to be put after the arguments, such
that "int c()[]" means the same as "int[] c()"

asmtest: avoid testing against complex nop alignment in gas
...
.align #,0x90 in gas ignores the 0x90 and outputs any kind
of nop it feels like. the one avoided by this patch is a 7
byte nop, which gas has been doing since at least 1999:
http://sourceware.org/ml/binutils/1999-10/msg00083.html
In order to match what gas does, we would need to make
code alignment target-specific, import a lot of code, and
face the question: exactly which gas {version,target,tune}
combo are we trying to match? see i386_align_code in:
http://sourceware.org/cgi-bin/cvsweb.cgi/src/gas/config/tc-i386.c?annotate=1.460&cvsroot=src
The smart noppery is turned on via the special casing of 0x90
