test/header-parsing.c: fix compiling failed while mips-gcc optimization enabled

There was an error about mips-gcc optimization while compiling
libsoup-2.4 2.45.3 with DEBUG_OPTIMIZATION enabled.

The test code of libsoup-2.4 2.45.3 triggered gcc assert which located
in gcc/dwarf2out.c:20810:
...
20806       gcc_assert (prev
20807                   && (CALL_P (prev)
20808                       || (NONJUMP_INSN_P (prev)
20809                           && GET_CODE (PATTERN (prev)) == SEQUENCE
20810                           && CALL_P (XVECEXP (PATTERN (prev), 0, 0)))));
...

The issue test code is the C function 'do_qvalue_tests' located in
tests/header-parsing.c.

The 2.45.92 have refactored the test code and this issue has been fixed.
So backport the fix to 2.45.3.

Upstream-Status: backport
