[CodeGen] Revamp counted_by calculations

Reformat with clang-format

Commits on Oct 30, 2023

Update testcase with anonymous structs and a union

Use 'IgnoreParenImpCasts' instead of just 'IgnoreImpCasts'

Use 'IgnoreParenImpCasts' and adjust code to use fewer 'Expr' variables.

Reduce number of const_casts.

Commits on Oct 31, 2023

Use 'getTypeSizeInChars' instead of dividing by 8

Use 'getTypeSizeInChars' instead of dividing by 8

Format

Use 'offsetof(struct s, array) + p->count * sizeof(*p->array)' instead of sizeof, which could emit an erroneous answer when alignment and padding are taken into account.

Commits on Nov 1, 2023

Adjust testcase to reflect 'offsetof' change.

Return the max of the struct size or offset + FAM size.

Small reordering of code and added more comments.

Commits on Nov 3, 2023

Support a __bdos() on an index into the FAM.

Commits on Nov 6, 2023

Merge branch 'llvm:main' into counted-by-expansion

Commits on Nov 8, 2023

Ignore parens for '&(p->fam[10])' expressions and use signed extend instead of unsigned.

Update testcase

Pass the signedness throughout the IR construction.

Commits on Nov 9, 2023

Start at the outer-most lexical RecordDecl instead of assuming the FAM was passed in here.

If the count is negative, we've gone past the end of the FAM. Return 0.
