The code executed by \pgfmathfloatifflags in the True case starts with a whitespace, caused by a missing % after the line

\if\pgfmathfloat@loc@TMPa#2

Here's a minimal example that demonstrates the error and the fix:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{fpu}
\begin{document}

\pgfkeys{/pgf/fpu}

\pgfmathparse{-1}
\fbox{\pgfmathfloatifflags{\pgfmathresult}{1}{T}{F}}

\pgfmathparse{1}
\fbox{\pgfmathfloatifflags{\pgfmathresult}{1}{T}{F}}

\makeatletter
\def\pgfmathfloatifflags#1#2#3#4{%
\if#2-%
\pgfmathfloatifflags{#1}{2}{#3}{#4}%
\else
\if#2+%
\pgfmathfloatifflags{#1}{1}{#3}{#4}%
\else
\pgfmathfloatgetflagstomacro#1\pgfmathfloat@loc@TMPa
\if#2u%
\ifnum\pgfmathfloat@loc@TMPa>2
#3\relax
\else
#4\relax
\fi
\else
\if\pgfmathfloat@loc@TMPa#2%
#3\relax
\else
#4\relax
\fi
\fi
\fi
\fi
}%
\makeatother

\pgfmathparse{-1}
\fbox{\pgfmathfloatifflags{\pgfmathresult}{1}{T}{F}}

\pgfmathparse{1}
\fbox{\pgfmathfloatifflags{\pgfmathresult}{1}{T}{F}}

\end{document}
