[PATCH] test regression fix: Remove xfail for variable length targets

[Juzhe-Zhong <juzhe.zhong@rivai.ai>]

Recently notice there is a XPASS in RISC-V:
XPASS: gcc.dg/vect/bb-slp-43.c -flto -ffat-lto-objects  scan-tree-dump-not slp2 "vector operands from scalars"
XPASS: gcc.dg/vect/bb-slp-43.c scan-tree-dump-not slp2 "vector operands from scalars"

And checked both ARM SVE and RVV:

https://godbolt.org/z/T9cPa7fh3

both has the same dump slp2. So I guess ARM SVE has the same XPASS in this test.

gcc/testsuite/ChangeLog:

	* gcc.dg/vect/bb-slp-43.c: Remove xfail for variable length.
