df99cfdf1e stage1: Fix typeInfo generation for arrays w/o sentinel 
ZigTypeIdOptional types have a different way of specifying their payload
value depending on whether the child type is a pointer or not (plus some
other special cases).

Fixes #7251

c80d196094 stage1: Add missing bitcast when rendering var ptr 
Some types require this extra bitcast, eg. structs or unions with extra
padding fields inserted by the compiler.

f91df39ad2 stage1: Fix crash in *[N]T to []T conversion with zst 
Prevent the crash by not making the codegen try to access the
non-existing ptr field in the slice.

58c2bec589 stage1: Fix ICE when generating struct fields with padding 
Make gen_const_ptr_struct_recursive aware of the possible presence of
some trailing padding by always bitcasting the pointer to its expected
type.

Not an elegant solution but makes LLVM happy and is consistent with how
the other callsites are handling this case.

Fixes #5398

7ebbc717c0 stage1: Fix generation of pass-by-value args in async fns

4d4ab1e69a stage1: Fix comparison of unions containing zero-sized types 
The code tried to be too smart and skipped the equality (returning true)
if the payload type was zero-sized.
This optimization is completely wrong when the union payload is a
metatype!

ff14451b4a std: Implement more useful approxEq semantics 
Comparisons with absolute epsilons are usually useful when comparing
numbers to zero, for non-zero numbers it's advised to switch to relative
epsilons instead to obtain meaningful results (check [1] for more
details).

The new API introduces approxEqAbs and approxEqRel, where the former
aliases and deprecated the old `approxEq`, allowing the user to pick the
right tool for the job.

The documentation is meant to guide the user in the choice of the
correct alternative.
