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

Updated solution is future proof for arbitary size integer handling for both strategies .br_table lowering if switch case is dense, .br_if base jump table if values are too sparse.

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.
