SVE intrinsics: Fold constant operands for svlsl.
This patch implements constant folding for svlsl. Test cases have been added to
check for the following cases:
Zero, merge, and don't care predication.
Shift by 0.
Shift by register width.
Overflow shift on signed and unsigned integers.
Shift on a negative integer.
Maximum possible shift, eg. shift by 7 on an 8-bit integer.
The patch was bootstrapped and regtested on aarch64-linux-gnu, no regression.
OK for mainline?
