[cfe-dev] clang installation size

[Paulo Matos via cfe-dev]

Hi,

I just cloned a llvm repo from github monolithic repo (release/8.x) and
compiled with under ArchLinux with the following arguments:
cmake -DCMAKE_INSTALL_PREFIX=/home/pmatos/installs/llvm-8x-head
-DCLANG_ANALYZER_ENABLE_Z3_SOLVER=ON -DLLVM_TARGETS_TO_BUILD=X86
-DLLVM_ENABLE_PROJECTS=clang ../llvm-project/llvm

I make and make install. Then I am shocked by the resulting install tree
size. That's 32Gb where bin is the largest folder with binaries as large
as 1.8 Gb, with clang and clangd being the largest ones.
-rwxr-xr-x 1 pmatos pmatos 1821621048 Mar 12 10:38 clang-8
-rwxr-xr-x 1 pmatos pmatos 1493399376 Mar 12 10:35 clangd

This is just ridiculously large. How can I reduce the size of these
binaries and the overall tree? I am compiling this to use `scan-build`
and `clang`, so is there a way to disable all the stuff I might not need?
