[PATCH] Fix a few typos and run-on sentences in the clang POD documentation.

[Brian R. Gaeke]

I realized that the first time I tried to send this, it went out
to the list without its patch attached.  Sorry about that. Here is
the patch. Comments appreciated.

 types for expressions as well and determine whether the code is well formed. This
 stage is responsible for generating most of the compiler warnings as well as
 parse errors.  The output of this stage is an "Abstract Syntax Tree" (AST).

 This stage translates an AST into low-level intermediate code (known as "LLVM
 IR") and ultimately to machine code.  This phase is responsible for optimizing
 the generated code and handling target-specific code generation.  The output of
