scanltranstree.exp defines some LTO wrappers around standard
non-LTO scanners. Four of them are cut-&-paste variants of
one another, so this patch generates them from a single template.
It also does the same for scan-ltrans-tree-dump-times, so that
other *-times scanners can be added easily in future.
The scanners seem to be lightly used. gcc.dg/ipa/ipa-icf-38.c uses
scan-ltrans-tree-dump{,-not} and libgomp.c/declare-variant-1.c
uses scan-ltrans-tree-dump-{not,times}. Nothing currently seems
to use scan-ltrans-tree-dump-dem*.
Tested on the files above so far. Surprisingly, it worked first time,
but I tested that deliberately introduced mistakes were flagged.
(That's my story anyway.) OK if it passes full testing on
aarch64-linux-gnu & x86_64-linux-gnu?

templates.
