additionally introduce a new file to centralize all the data about
builtin functions that we have, including:
* enum tag identifying the builtin function
* number of parameters.
* whether the expression may need a memory location.
* whether the expression allows an lvalue (currently only true for
`@field`).
Now there is only one ComptimeStringMap that has this data as the value,
and we dispatch on the enum tag in order to asgen the builtin function.
In particular this simplifies the logic for checking the number of
parameters.
This removes some untested code paths from if and while, which need to
be restored with #7929 in mind.
After this there are only a handful left of expression types to rework
to the new memory layout, and then it will be only compile errors left
to solve.
break, continue, blocks, bit_not, negation, identifiers, string
literals, integer literals, inline assembly
also gave multiline string literals a different node tag from regular
string literals, for code clarity and to avoid an unnecessary load from
token_tags array.

I resolved some of the conflicts by reverting a small portion of
@tadeokondrak's stage2 logic here regarding `callconv(.Inline)`.
It will need to get reworked as part of this branch.
This commit does not reach any particular milestone, it is
work-in-progress towards getting things to build.
There's a `@panic("TODO")` in translate-c that should be removed when
working on translate-c stuff.
I've added more of the ".def" files from mingw. The list is based on all the libraries referenced by the win32metadata project. (see https://github.com/marlersoft/zigwin32).
