donghanyuan b0d1b02859 replace local static allocator to global static 
Ensure MemoryPool construct before SimPlatform,
thus MemoryPool destruct after SimPlatform.

Avoid use-after-free issue clearing events_ of SimPlatform
after SimPortEvent's allocator is destructed.

Toolchain Dependencies

Install development tools

$ sudo apt-get install build-essential
$ sudo apt-get install git

Install Vortex codebase

$ git clone --recursive https://github.com/vortexgpgpu/vortex.git
$ cd Vortex

Install prebuilt toolchain

By default, the toolchain will install to /opt folder. 
You can install the toolchain to a different directory by overriding TOOLDIR (e.g. export TOOLDIR=$HOME/tools).

$ ./ci/toolchain_install.sh --all
$ source ./ci/toolchain_env.sh

Build Vortex sources

$ make -s
