Our previous approach of creating a union from individual special
integer bitfields leads to undefined values because only one member of a
union can be active at any given time. Compilers have finally caught up
with us on that and have started removing "no-op" writes to members.
The primary user of the special integer bitfield unions is
qv4compileddata_p.h in qtdeclarative. We want our on-disk format of
QML compilation units to be platform agnostic and space efficient.

The `inline` keyword does not control inlining, as we all know (use
Q_ALWAYS_INLINE to force inlining, if required). However, it does
control the emission of the out-of-line copy of an inline function, if
the compiler did inline it where it got used: with the keyword, no copy
is required, which is our objective here.
Furthermore, we compile with -fvisibility-inlines-hidden with
GCC-compatible compilers (all but MSVC and Integrity's), which means
those functions will never be in the ABI of QtCore: they'll either have
been inlined with no out-of-line copy, or that out-of-line emission is
hidden.

So if the indicator is styled, then we have to draw an otherwise empty

This is particularly problematic when combined with version checks:

correct way (until a new kid on the block starts to mask as GCC, too)
to check for GCC >= 9.0 atm is:
#if defined(Q_CC_CLANG) || defined(Q_CC_INTEL) || !(defined(Q_CC_GNU) && Q_CC_GNU >= 900)
