Problem: Vim9: script cannot use line continuation like in a :def function.
Solution: Pass the getline function pointer to the eval() functions. Use it
for addition and multiplication operators.

vim-patch:8.2.0753: Vim9: expressions are evaluated in the discovery phase
Problem: Vim9: expressions are evaluated in the discovery phase.
Solution: Bail out if an expression is not a constant. Require a type for
declared constants.

vim-patch:8.2.0818: Vim9: using a discovery phase doesn't work well
Problem: Vim9: using a discovery phase doesn't work well.
Solution: Remove the discovery phase, instead compile a function only when
it is used. Add :defcompile to compile def functions earlier.

* fix(PVS/V009): start file with special comment
* fix(PVS/V501): identical sub-expressions for comparison

Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
Problem: Bogus error when string used after :elseif.
Solution: Do not consider a double quote the start of a comment.

Omit ends_excmd2(): the same as ends_excmd() in legacy Vim script.
Co-authored-by: Bram Moolenaar <Bram@vim.org>
`!did_throw` doesn't exactly imply `!current_exception`, as `did_throw = false`
is sometimes used to defer exception handling for later (without forgetting the
exception). E.g: uncaught exception handling in `do_cmdline()` may be deferred
to a different call (e.g: when `try_level > 0`).
In #7881, `current_exception = NULL` in `do_cmdline()` is used as an analogue of
`did_throw = false`, but also causes the pending exception to be lost, which
also leaks as `discard_exception()` wasn't used.
It may be possible to fix this by saving/restoring `current_exception`, but
handling all of `did_throw`'s edge cases seems messier. Maybe not worth
diverging over.
This fix also uncovers a `man_spec.lua` bug on Windows: exceptions are thrown
due to Windows missing `man`, but they're lost; skip these tests if `man` isn't
executable.
Problem: Vim9: 'cpo' can become empty.
Solution: Use empty_option instead of an empty string. Update quickfix
buffer after restoring 'cpo'. (closesvim/vim#7608)

Omit test as it is Vim9 script.
Problem: When a test fails it's often not easy to see what the call stack
is.
Solution: Add more entries from the call stack in the exception message.
a5d0423fa1
Use docs from latest Vim.
Problem: Vim9: script reload test is disabled.
Solution: Compile a function in the context of the script where it was
defined. Set execution stack for compiled function. Add a test
that an error is reported for the right file/function.

Omit stack_top_is_ufunc(): only used by Vim9 script.
Problem: Execution stack is incomplete and inefficient.
Solution: Introduce a proper execution stack and use it instead of
sourcing_name/sourcing_lnum. Create a string only when used.

Omit test_debugger.vim: superseded by later patches.
Omit check_map_keycodes(): N/A.
Omit kword_test.c: N/A (converted to a unit test).
Problem: Ex command error cannot contain an argument.
Solution: Add ex_errmsg() and translate earlier. Use e_trailing_arg where
possible.
