Sema: allow @ptrCast slice of zero-bit type to slice of non-zero-bit type
This is actually completely well-defined. The resulting slice always has
0 elements. The only disallowed case is casting *to* a slice of a
zero-bit type, because in that case, you cna't figure out how many
destination elements to use (and there's *no* valid destination length
if the source slice corresponds to more than 0 bits).

Sema: fix in-memory coercion of functions introducing new generic parameters
While it is not allowed for a function coercion to change whether a
function is generic, it *is* okay to make existing concrete parameters
of a generic function also generic, or vice versa. Either of these cases
implies that the result is a generic function, so comptime type checks
will happen when the function is ultimately called.

x86_64: implement integer saturating left shifting codegen
Simliarly to shl_with_overflow, we first SHL/SAL the integer, then
SHR/SAR it back to compare if overflow happens.
If overflow happened, set result to the upper limit to make it saturating.

Bug: #17645

std.Target: Remove functions that just wrap component functions.
Functions like isMinGW() and isGnuLibC() have a good reason to exist: They look
at multiple components of the target. But functions like isWasm(), isDarwin(),
isGnu(), etc only exist to save 4-8 characters. I don't think this is a good
enough reason to keep them, especially given that:

* It's not immediately obvious to a reader whether target.isDarwin() means the
  same thing as target.os.tag.isDarwin() precisely because isMinGW() and similar
  functions *do* look at multiple components.
* It's not clear where we would draw the line. The logical conclusion before
  this commit would be to also wrap Arch.isX86(), Os.Tag.isSolarish(),
  Abi.isOpenHarmony(), etc... this obviously quickly gets out of hand.
* It's nice to just have a single correct way of doing something.
