e3c92d0532 ir: More changes to sentinel-terminated const arrays 
* Don't add an extra slot for the sentinel. Most of the code keeps using
  the constant value from the type descriptor, let's harmonize all the
  code dealing with sentinels.

* Properly write out sentinel values when reinterpreting pointers at
  comptime.

* Allow the reading of the 0th element in a `[0:S]T` type.

46ffc798b6 fix swapped logic for Windows 
Remove `std.fs.deleteTree`. Callers instead should use
`std.fs.cwd().deleteTree`.

Add `std.fs.deleteTreeAbsolute` for when the caller has an absolute
path.

7aac21c6f5 allow _ separators in number literals (stage 1) 
* Underscores `_` may be placed between two digits in a int/float literal
* Consecutive underscores are not allowed
* Fixed parsing bug in exponents of hexadecimal float literals.
  Exponents should always be base 10, but hex characters would be parsed
  inside the exponent and everything after them would be ignored. eg:
  `0x1.0p1ab1` would be parsed as `0x1.0p1`.

fa46bcb368 stage1: make get_optional_type more robust 
Now it will emit a compile error rather than crashing when the child
type has not been resolved properly.

Introduces `get_optional_type2` which should be used generally inside
ir.cpp.

Fix some std lib compile errors noticed by the provided test case.

Thanks @LemonBoy for the test case. Closes #4377.

Fixes #4374.
