CHANGES: * Wrap library into `GoblintCil` module (goblint/cil#107). * Remove all MSVC support (goblint/cil#52, goblint/cil#88). * Port entire build process from configure/make to dune (goblint/cil#104). * Add C11 `_Generic` support (goblint/cil#48). * Add C11 `_Noreturn` support (goblint/cil#58). * Add C11 `_Static_assert` support (goblint/cil#62). * Add C11 `_Alignof` support (goblint/cil#66). * Add C11 `_Alignas` support (goblint/cil#93, goblint/cil#108). * Add partial C11 `_Atomic` support (goblint/cil#61). * Add `_Float32`, `_Float64`, `_Float32x` and `_Float64x` type support (goblint/cil#8, goblint/cil#60). * Add Universal Character Names, `char16_t` and `char32_t` type support (goblint/cil#80). * Change locations to location spans and add additional expression locations (goblint/cil#51). * Add synthetic marking for CIL-inserted statement locations (goblint/cil#98). * Expose list of files from line control directives (goblint/cil#73). * Add parsed location transformation hook (goblint/cil#89). * Use Zarith for integer constants (goblint/cil#47, goblint/cil#53). * Fix constant folding overflows (goblint/cil#59). * Add option to disable constant branch removal (goblint/cil#103). * Add standalone expression parsing and checking (goblint/cil#97, goblint/cil#96). * Improve inline function merging (goblint/cil#72, goblint/cil#85, goblint/cil#84, goblint/cil#86). * Fix some attribute parsing cases (goblint/cil#71, goblint/cil#75, goblint/cil#76, goblint/cil#77). * Fix global NaN initializers (goblint/cil#78, goblint/cil#79). * Fix `cilly` binary installation (goblint/cil#99, goblint/cil#100, goblint/cil#102). * Remove batteries dependency to support OCaml 5 (goblint/cil#106).

This adds a function
Check.checkStandaloneExpwhich allows checking a standalone expression (not an entirefile). It allows working around #95 (and maybe #94) by first checking if the invariant parsed from a witness has valid AST and ignoring the invalid ones. This is better than having the respective crash come from deep within Goblint, where it's not obvious whose fault it is, and prevents garbage-in–garbage-out.
