[truetype] Fix change from 2013-11-20.

Problem reported by Akira Kakuto <kakuto@fuk.kindai.ac.jp>.

* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Protect call to
`Update_Max' with both a TT_USE_BYTECODE_INTERPRETER guard and a
`IS_HINTED' clause.
Also remove redundant check using `maxSizeOfInstructions' – in
simple glyphs, the bytecode data comes before the outline data, and
a validity test for this is already present.
Formatting.
[truetype] Fix phantom point handling.

This is a further improvement to the changes from 2013-11-06.

* src/truetype/ttgload.c (TT_Hint_Glyph): Horizontal phantom points
are rounded horizontally, vertical ones are rounded vertically.
(TT_LOADER_SET_PP): The horizontal position of vertical phantom
points in pre-ClearType mode is zero, as shown in the OpenType
specification.
[truetype] Remove dead code.

Reported by Nigel Tao <nigeltao@golang.org>.

* include/internal/tttypes.h (TT_LoaderRec): Remove unused
`preserve_pps' field.
* src/truetype/ttgload.c (TT_Hint_Glyph): Updated.
[sfnt] Fix handling of embedded bitmap strikes.

This corrects the commit from 2013-11-21.  Problem reported by
Andrey Panov <panov@canopus.iacp.dvo.ru>.

* src/sfnt/ttsbit.c (tt_sbit_decoder_load_bitmap): Fix logic to
detect excessive bytes for bit-aligned bitmaps.
* builds/freetype.mk (FT_CC): Removed.  Unused.
[truetype] Next round in phantom point handling.

Greg Hitchcock provided very interesting insights into the
complicated history of the horizontal positions of the TSB and BSB
phantom points.

* src/truetype/ttgload.c (TT_LOADER_SET_PP)
[TT_CONFIG_OPTION_SUBPIXEL_HINTING]: Use `subpixel_hinting' and
`grayscale_hinting' flags as conditionals for the x position of TSB
and BSB.
Add info on bytecode interpreter versions of Windows.
