Subject: [PATCH] BPF: Add LLVMAnalysis in CMakefile LINK_COMPONENTS

buildbot reported a build error like below:
  BPFTargetMachine.cpp:(.text._ZN4llvm19TargetTransformInfo5ModelINS_10BPFTTIImplEED2Ev
    [_ZN4llvm19TargetTransformInfo5ModelINS_10BPFTTIImplEED2Ev]+0x14):
    undefined reference to `llvm::TargetTransformInfo::Concept::~Concept()'
  lib/Target/BPF/CMakeFiles/LLVMBPFCodeGen.dir/BPFTargetMachine.cpp.o:
    In function `llvm::TargetTransformInfo::Model<llvm::BPFTTIImpl>::~Model()':

Commit a260ae716030 ("BPF: Implement TTI.IntImmCost() properly")
added TargetTransformInfo to BPF, which requires LLVMAnalysis
dependence. In certain cmake configurations, lacking explicit
LLVMAnalysis dependency may cause compilation error.
Similar to other targets, this patch added LLVMAnalysis
in CMakefile LINK_COMPONENTS explicitly.
