[Bug target/40983] New: The scheduler incorrectly swaps MMX and floating point instructions

["mikulas at artax dot karlin dot mff dot cuni dot cz" <gcc-bugzilla at gcc dot gnu dot org>]

Hi

This example fails, because in function "f", the scheduler incorrectly swapped
floating point store to "c" and load of mmx registers.

Compile with -O2 -march=pentium-mmx
