    This change extends the work in https://golang.org/cl/51131 to include
    placeholder pointer types created for Go function types, which can
    also be left dangling/unresolved in some instances. This fixes an
    assert in Llvm_backend::materializeComposite.
    
    Test case can be found in https://golang.org/cl/191743.

This patch allows users of the substitute_and_fold_engine to
enable folding all statements.  It is now enabled for VRP which
is needed for the match.pd pattern in patch 2/2.

The loop versioning pass was missing one case when
deconstructing addresses that would only be triggered after
this patch for me:
It could handle addition and subsequent convert/nop but not
a convert/nop directly.  This would cause the hash to be
calculated differently and, in turn, cause the pass to miss
a versioning opportunity.  Fixed this by adding the missing
case.

    Record when a local pointer variable is set to a value such that
    indirecting through the pointer does not require a write barrier.  Use
    that to eliminate write barriers when indirecting through that local
    pointer variable.  Only keep this information per-block, so it's not
    all that applicable.
    
    This reduces the number of write barriers generated when compiling the
    runtime package from 553 to 524.
    
    The point of this is to eliminate a bad write barrier in the bytes
    function in runtime/print.go.  Mark that function nowritebarrier so
    that the problem does not recur.

We used to implement darn with unspecs, not unspec_volatiles, which
means two darn instructions could be CSEd together.

This testcase tests it by adding together four random numbers.  If all
is well that means we get four darn instructions, because such a small
loop is unrolled fine at -O2 already.  If things go bad, combine will
combine it all to one darn and a shift left by two.

Note 1: I haven't run the testsuite with this patch, but it fixes the
build failure I see (in sources with other local changes).

Note 2: I don't know why this hasn't produced build failures for other

Prevent lines overlapping the right hand margin, this occurred for
references in the "See also:" section, it is prevented by placing
references on their own lines. Two example programs overlapped the
right hand margin: fixed by adjusting the position and of the comments.
Some tables had overlapping colums: the column widths were adjusted
accordingly.

When we are parsing a source file, the very first token might
be a PRAGMA_GCC_PCH_PREPROCESS.  This indicates that we are going
read in a PCH file (named as the value of the pragma).  If we don't
see this pragma, then we know that it's OK to release any resources
that the host might have set aside for the PCH file.

This fixes a thinko in the current implementation, in that the decision
to release resources was happening unconditionally right after the first
token is extracted but before it's been checked or acted upon.

This leads to the pch bug (seen on Darwin), because we actually do release
resources - which are subsequently (reasonably) assumed to be available
when reading a PCH file.  We then get random crashes or hangs depending
on the interaction between unmmap and malloc.

The bug is present everywhere but doesn't show on (say) Linux, since
the release of PCH resources is a NOP there.

This effects all the c-family front ends, because they all use c_lex_with_flags ()
to implement this.

The solution is to check for the PRAGMA_GCC_PCH_PREPROCESS and only call
c_common_no_more_pch () when that is not the first token.

A secondary effect of the collection is that the name of the PCH file
can be collected during the ggc_pch_read() reset of state.  Therefore
we should issue any diagnostic that might name the file before the
collections are triggered.
