Crash in QDeclarativeCompiler::indexOfProperty

In QDeclarativePropertyCache, plain integer bitfield overrideIndex is
initialized with -1 in class constructor. Unfortunately, ARM compiler
treats bitfields as unsigned, unless explicitly defined as signed [1].
Therefore, overrideIndex actually gets initial value of 2147483647,
which causes array operations done with the index to fail.

As a fix, define overrideIndex as signed int bitfield.

Under bitfields/Note: "A plain bitfield, declared without either
signed or unsigned qualifiers, is treated as unsigned"
