Behdad Esfahbod 96828b97a8 [layout] Minor

Behdad Esfahbod 5739c876d0 [test] Rename some fonts 
If we have duplicae font files in different directories, that would
break the oss-fuzz build currently.  So, rename some to avoid
name class with text-rendering-test.  Would be better to find
another solution.

Ben Wagner 94e421abbf Remove some use of Crap in hb-set. 
When hb_set_t::page_for_insert needs to insert at the end of the page_map
it ends up evaluating '&page_map[i + 1]' which has hb_vector return an
lvalue of a Crap so that nothing can be moved to its address. This turns
into issues with ThreadSanitizer on Crap when two threads modify different
hb_set_t instances. This can be avoided by using '&page_map[i] + 1'
instead.

Behdad Esfahbod 401cdf0792 [ot-font] Fix sign of ascent/descent 
Some fonts, like msmincho, have positive number as descent
in vhea table.  That's wrong.  Just enforce sign on ascent/descent
when reading both horizontal and vertical metrics.

Behdad Esfahbod 792071de40 [morx] Leave ligature on stack after ligating 
Test with Apple Color Emoji.ttf of ~66MB and following sequence:

./hb-shape Apple\ Color\ Emoji-old.ttf --font-funcs=ot -u U+1F468,200d,U+1F469,200d,U+1F467,200d,1f466

Should form full family if matching works correctly.  It first makes
family of three, then makes family of four out of that and the last
two characters.

[ci] Disable llvm-gcc 
#define Null(Type) Null<typename hb_remove_const<typename hb_remove_reference<Type>::value>::value>()

raises:
  hb-blob.cc: In function 'hb_blob_t* hb_blob_get_empty()':
  hb-blob.cc:194: error: using 'typename' outside of template
  hb-blob.cc:194: error: using 'typename' outside of template

Removing "typename"s fixes the issue but makes newer compiler fail apparently.

Probably downstream can patch that locally till we get a solution.
