[committed] analyzer: fix testsuite assumption that sizeof(int) > 2

[David Malcolm]

Fix some failures on xstormy16-elf:
  gcc.dg/analyzer/data-model-1.c  (test for warnings, line 595)
  gcc.dg/analyzer/data-model-1.c  (test for warnings, line 642)
  gcc.dg/analyzer/data-model-1.c  (test for warnings, line 690)
  gcc.dg/analyzer/data-model-1.c  (test for warnings, line 738)

due to:

warning: overflow in conversion from ‘long int’ to ‘int’ changes
  value from ‘100024’ to ‘-31048’ [-Woverflow]
    20 |   p[0].x = 100024;
       |            ^~~~~~


Successfully bootstrapped & regrtested on x86_64-pc-linux-gnu.

Manually verified on a stage1 --target=xstormy16-elf without asm
support; appears to now be correct there.

Pushed to master as c422cec54a5495f6f42b80f35a11c5508fe8eec3.

        from int to long.
