text/template: reduce maxExecDepth for gccgo further

    We already lowered the limit of recursive template invocations from
    100,000 to 10,000, but the tests still fail occasionally on
    x86_64-pc-linux-gnu when using GNU ld (so that split stacks are not
    fully functional).  Reduce the limit further, to 1000, enough so that

PR go/72814

    runtime: treat zero-sized result value as void

    Change the FFI interface to treat a call to a function that returns a
    zero-sized result as a call to a function that returns void.

    This is part of the fix for https://gcc.gnu.org/PR72814.  On 32-bit
    SPARC systems, a call to a function that returns a non-zero-sized struct
    is followed by an unimp instruction that describes the size of the
    struct.  The function returns to the address after the unimp
    instruction.  The libffi library can not represent a zero-sized struct,
    so we wind up treating it as a 1-byte struct.  Thus in that case libffi
    calls the function with an unimp instruction, but the function does not
    adjust the return address.  The result is that the program attempts to
    execute the unimp instruction, causing a crash.

    This is part of a change that fixes the crash by treating all functions
    that return zero bytes as functions that return void.

[RS6000] PR72802 part 2, reload ICE

After fixing the constraint problem, we hit an "insn does not satisfy
its constraints" with -mno-lra on the following insn, a vector load
from mem which has an invalid offset:
(insn 631 630 1122 12 (set (reg:SF 108 31 [orig:260 pretmp_44 ] [260])
        (mem:SF (plus:DI (reg:DI 30 30 [orig:338 ivtmp.141 ] [338])
                (const_int 2 [0x2])) [5 MEM[base: _1, offset: 2B]+0 S4 A32])) 470 {movsf_hardfloat}
     (nil))

Here are the reload costs for the various alternatives of
movsf_hardfloat:
"=!r, !r,  m,  f, ww, ww, !r,  f, wb,  m, wY, wu,  Z,?wn, ?r,*c*l, !r, *h"
  "r,  m,  r,  f, ww,  j,  j,  m, wY,  f, wb,  Z, wu,  r, wn,   r, *h,  0"
 617 609  17  17   8   8 617   9   8  17  17   8  17  23  23   17 617  17

Notice that the cost for a vector<-vector move (ww,ww) is the same as
the cost for a vector<-mem move (wb,wY or wu,Z).  Since the
vector<-vector move comes first, it is chosen and the mem part of the
insn reloaded.  That just gives another copy of insn 631.

[RS6000] PR72802 part 1, fix constraints for lxssp/stxssp

We can't use "o" constraint for lsxxp/stxssp since those insns have a
DS-form offset field, ie. the bottom two bits of the offset must be 0.
So use "wY" instead, but that leads to finding another problem.

mem_operand_gpr is only suitable for gpr loads/stores since it does
not enforce multiple-of-4 offsets when -m32.  So "wY" can't use
mem_operand_gpr, and the vsx tests in mem_operand_gpr are bogus.

I've deleted offsettable_mem_14bit_operand because it wasn't used
anywhere but in the wY constraint.  Note also that the new wY
constraint doesn't use memory_operand because that is redundant in a
constraint, having already been tested in the predicate.

libgo: change build procedure to use build tags

    Previously the libgo Makefile explicitly listed the set of files to
    compile for each package.  For packages that use build tags, this
    required a lot of awkward automake conditionals in the Makefile.

    This CL changes the build to look at the build tags in the files.
    The new shell script libgo/match.sh does the matching.  This required
    adjusting a lot of build tags, and removing some files that are never
    used.  I verified that the exact same sets of files are compiled on
    amd64 GNU/Linux.  I also tested the build on i386 Solaris.

    Writing match.sh revealed some bugs in the build tag handling that
    already exists, in a slightly different form, in the gotest shell
    script.  This CL fixes those problems as well.

    The old code used automake conditionals to handle systems that were
    missing strerror_r and wait4.  Rather than deal with those in Go, those
    functions are now implemented in runtime/go-nosys.c when necessary, so
    the Go code can simply assume that they exist.

    The os testsuite looked for dir_unix.go, which was never built for gccgo
    and has now been removed.  I changed the testsuite to look for dir.go
    instead.
