[testsuite] disable PIE on ia32 on more tests

Multiple tests fail on ia32 with -fPIE enabled by default because of
different call sequences required by the call-saved PIC register
(no-callee-saved-*.c), uses of the constant pool instead of computing
constants (pr100865-*.c), and unexpected matches of esp in get_pc_thunk
(sse2-stv-1.c).  Disable PIE on them, to match the expectations.
