Обсуждение: pgsql: Fix allocation formula in llvmjit_expr.c

Fix allocation formula in llvmjit_expr.c

An array of LLVMBasicBlockRef is allocated with the size used for an
element being "LLVMBasicBlockRef *" rather than "LLVMBasicBlockRef".
LLVMBasicBlockRef is a type that refers to a pointer, so this did not
directly cause a problem because both should have the same size, still
it is incorrect.

This issue has been spotted while reviewing a different patch, and
exists since 2a0faed9d702, so backpatch all the way down.
