Add support for VFLAGS environment variable, merged with cmd args. Using VFLAGS, you can pass common options through it to the V compiler, without having to manually specify them everytime when you type V ... In addition, since environment variables are *inherited*, all subprocess V compilers, which V launches (for example when compiling with -live), will *also* use the same VFLAGS environment variable. Example usage: export VFLAGS="-debug -show_c_cmd" v -live message.v => This will keep *both* of the generated C source files .message.c *AND* .message_shared_lib.c . It will also cause both V compile subprocesses to print their resulting C compiler backend lines. This is very useful when using GDB to debug problems.
