* line tables and backtraces: port agent/line-tables onto main, op 56 on the ↵Gravatar zinc 13 days1-0/+1

* zc: add the defer statementGravatar zinc 13 days1-0/+1
| | | | | | | | | | | | defer expr; and defer { ... } register code that runs when the enclosing block ends: at the end of the block, and at return, break and continue that leave it. the tokens are kept at the defer and compiled again at each exit (block_close, body, kw_return, kw_break, kw_continue), newest first, before the block's variables are released, so the analyzer sees a deferred rt.free(p) as the transfer of p where it runs. names mean what they meant at the defer; values are read when it runs. return, break and continue inside a deferred statement are errors, reported once. works in unchecked code and closures (own base per function context).
* split compiler.zc into files by phaseGravatar zinc 13 days1-0/+191
src/compiler/compiler.zc is now twelve files under src/compiler/, listed in order in src/compiler/parts. cat of the parts in order is byte-identical to the old file, so every compiler and image except the language server's is unchanged. no function was edited. consumers read the list: the makefile, bootstrap-check, genmap (which still writes one compiler.zc into a generated map directory), tinyvm.bat, test.sh, test_win.ps1 and the lsp drivers. the language server embeds each part and serves them joined as the one document tinyvm:/compiler.zc.
