e3f5edb577 Don't distribute percentage width from column-spanning cells to columns that have no cells originating. (Bug 810586) r=dholbert 
This makes the distribution of pref/min width and the distribution of
percentage width from column-spanning cells more consistent with each
other.  Having them inconsistent means that a column-spanning cell that
has both percentage width and minimum intrinsic width might distribute
those widths among its columns differently, which can then lead to the
percentages unnecessarily increasing the table's preferred intrinsic
width.

(It *might* also be worth fixing the FLEX_ALL_LARGE case in
DistributeWidthToColumns to also check for originating cells, since it's
now the only case that doesn't, except that we can't guarantee that
there are columns with originating cells, so it would really require
splitting that case, which is extra complexity that doesn't seem worth
it for such a rarely-hit and non-interoperable case.)

43e58e33c8 Bug 760331: Coalesce data for inline style across nodes. r=bz 
This patch enables sharing of an nsAttrValue's MiscContainer between nodes for style rules.  MiscContainers of type eCSSStyleRule are now refcounted (with some clever struct packing to ensure that the amount of memory allocated for MiscContainer remains unchanged on 32 and 64 bit).  This infrastructure can be used to share most MiscContainer types in the future if we find advantages to sharing other types than just eCSSStyleRuley.  A cache mapping strings to MiscContainers has been added to nsHTMLCSSStyleSheet.  MiscContainers can be shared between nsAttrValues when one nsAttrValue is SetTo another nsAttrValue or when there is a cache hit in this cache.  This patch also adds the ability to tell a style rule that it belongs to an nsHTMLCSSStyleSheet, with appropriate accessor functions to separate that from the existing case of belonging to an nsCSSStyleSheet.

The primary use case is to reduce memory use for pages that have lots of inline style attributes with the same value.  This can happen easily with large pages that are automatically generated.  An (admittedly pathological) testcase in Bug 686975 sees over 250 MB of memory savings with this change.  Reusing the same MiscContainer for multiple nodes saves the overhead of maintaining separate copies of the string containing the serialized value of the style attribute and of creating separate style rules for each node.  Eliminating duplicate style rules enables further savings in layout through style context sharing.  The testcase sees the amount of memory used by style contexts go from over 250 MB to 10 KB.

Because the cache is based on the text value of the style attribute, it will not handle attributes that have different text values but are parsed into identical style rules.  We also do not attempt to share MiscContainers when the node's base URI differs from the document URI.  The effect of these limitations is expected to be low.

90733eea84 Add a font inflation data structure per block formatting context. (Bug 706193, patch 2) r=roc 
This structure is per block formatting context because we have to make a
single inflation decision for things like consecutive runs of paragraphs
of text.  Inflating some paragraphs and not others (within the same
sequence of adjacent paragraphs) based on the amount of text in each one
would be disastrous.  Otherwise it's ideal for the units to be as small
as possible as long as they merge such sequences; therefore this uses a
definition corresponding to CSS's idea of elements that establish new
block formatting contexts.

bf5a330929 Bug 735898. Part 3: In DisplayBorderBackgroundOutline, when we have created an nsDisplayBackground item and it's themed, don't bother checking to create an nsDisplayBorder item. r=mattwoodrow 
It turns out that calling HasBorder() is especially expensive for themed frames since we call into the theme engine to compute the border, so avoiding it is a nice win.
