LoongArch: Opitmize the cost of vec_construct.
When analyzing 525 on LoongArch architecture, it was found that the
for loop of hotspot function x264_pixel_satd_8x4 could not be quantized
256-bit due to the cost of vec_construct setting. After re-adjusting
vec_construct, the performance of 525 program was improved by 16.57%.
It was found that this function can be vectorized on the aarch64 and
x86 architectures, see [PR98138].

gcc/ChangeLog:
* config/loongarch/loongarch.cc
(loongarch_builtin_vectorization_cost): Modify the
construction cost of the vec_construct vector.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/vect-slp-two-operator.c: New test.
