Replace heap-allocated list of chars with QStringLiteral
The main bottleneck in the benchmark for KTextToHTML was actually
constructing the temporary list of word-boundaries. Instead of
doing that all the time, use a QStringLiteral-constructed static
QString.
This improves the benchmarks by more than ~4x on my machine,
all compiled in RelWithDebInfo:
PASS : KTextToHTMLTest::benchHtmlConvert(plain)
RESULT : KTextToHTMLTest::benchHtmlConvert():"plain":
0.75 msecs per iteration (total: 96, iterations: 128)
PASS : KTextToHTMLTest::benchHtmlConvert(preserve-spaces)
RESULT : KTextToHTMLTest::benchHtmlConvert():"preserve-spaces":
0.71 msecs per iteration (total: 91, iterations: 128)

0.75 msecs per iteration (total: 96, iterations: 128)
PASS : KTextToHTMLTest::benchHtmlConvert(preserve-spaces+highlight-text)
RESULT : KTextToHTMLTest::benchHtmlConvert():"preserve-spaces+highlight-text":
0.79 msecs per iteration (total: 51, iterations: 64)
PASS : KTextToHTMLTest::benchHtmlConvert(preserve-spaces+highlight-text+replace-smileys)
RESULT : KTextToHTMLTest::benchHtmlConvert():"preserve-spaces+highlight-text+replace-smileys":
0.79 msecs per iteration (total: 51, iterations: 64)
Remove temporary string allocations
Instead of calling .mid() to compare to a QLatin1String,
call .midRef() as that won't allocate.
Improves the performance of the unit test by ~2x on my
machine when compiling in RelWithDebInfo:
