better string literal caching implementation 
We were caching the ConstExprValue of string literals,
which works if you can never modify ConstExprValues.
This premise is broken with `comptime var ...`.

So I implemented an optimization in ConstExprValue
arrays, where it stores a `Buf *` directly rather
than an array of ConstExprValues for the elements,
and then similar to array of undefined, it is
expanded into the canonical form when necessary.
However many operations can happen directly on the
`Buf *`, which is faster.

Furthermore, before a ConstExprValue array is expanded
into canonical form, it removes itself from the string
literal cache. This fixes the issue, because before an
array element is modified it would have to be expanded.

1b3aaacba2 Removed copy-pasted resolve_inferred_error_set 
both ir.cpp and analyze.cpp have a function resolve_inferred_error_set,
which is a nearly exact copy-paste. This commit removes the one in ir.cpp
and exposes then one in analyze.cpp. This also allows us to make
analyze_fn_body local to analyze.cpp, as it is not used anywhere in
ir.cpp after this change

aa2995ee39 fix invalid codegen for error return traces across suspend points 
See #821

Now the code works correctly, but error return traces are missing
the frames from coroutines.

84e952c230 fix await multithreaded data race 
coro return was reading from a value that coro await was
writing to. that wasn't how it was designed to work, it
was an implementation mistake.

this commit also has some work-in-progress code for fixing
error return traces across suspend points.
