Sema: error on ambiguous coercion of comptime float and ints
...
The following, from the documentation as of the time of writing, illustrates
the problem:
```zig
// Compile time coercion of float to int
test "implicit cast to comptime_int" {
var f: f32 = 54.0 / 5;
_ = f;
}
```
It is not clear how to unify the types of 54.0 and 5 to perform the
division. We can either
- cast 54.0 to comptime_int resulting in @as(comptime_int, 10), which is
casted to @as(f32, 10), or
- cast 5 to comptime_float resulting in @as(comptime_float, 10.8), which
is casted to @as(f32, 10.8)
Since the two resulting values are different, a compiler error is appropriate.
If we know that casting to either type will result in the same value we
don't need to error. For instance, 10.0 / 2 is okay, as is 10 / 2.0.

libstd: fix off-by-one error in def of ProcSym in pdb
...
Make sure `ProcSym` includes a single element byte-array which delimits
the start of the symbol's name as part of its definition. This makes
the code more elegant in that accessing the name is equivalent to taking
the address of this one element array.

Sema: fix generics with struct literal coerced to tagged union
...
The `Value.eql` function has to test for value equality *as-if* the lhs
value parameter is coerced into the type of the rhs. For tagged unions,
there was a problematic case when the lhs was an anonymous struct,
because in such case the value is empty_struct_value and the type
contains all the value information. But the only type available in the
function was the rhs type.
So the fix involved making `Value.eqlAdvanced` also accept the lhs type,
and then enhancing the logic to handle the case of the `.anon_struct` tag.

This improves the following test case:
```zig

fn foo() !void {

The error return trace now points to the `try` token instead of pointing
to the foo() function call, matching stage1.
