This is an attempt to feature the user-facing resources more
prominently on the LLDB website by calling out the tutorial and the
GDB command map wight on the start page.
I also moved the "Why a new debugger" section to the "Goals"
subpage. Given that LLDB's first release is almost a decade in the
past now, the title is a bit of an anachronism.
Lastly, I moved the Architecture sub-page from "use" to "resources",
since end-users do not care about the source code layout.
Differential Revision: https://reviews.llvm.org/D70449
This renames the "Goals & Status" section to "Project" and the
"Resources" section to "Development". To better match this layout I've
moved the releases page under "Project".
The page describing how to get the sources was more about contributing
to LLDB than getting the actual source. This patch moves some things
around and repurposes this page as a contributing to LLDB landing page.
