[Clang] Convert various tests to opaque pointers (NFC) These were all tests where no manual fixup was required.

[CodeGen] Add additional mangling for struct members of non trivial structs In https://bugs.llvm.org/show_bug.cgi?id=41206 we observe bad codegen when embedding a non-trivial C struct within a C struct. This is due to the fact that name mangling for non-trivial structs marks the two structs as identical. This diff contains a fix for this issue. Patch by Dan Zimmerman <daniel.zimmerman@me.com>. Differential Revision: https://reviews.llvm.org/D59873 llvm-svn: 357184

Use functions with prototypes when appropriate; NFC A significant number of our tests in C accidentally use functions without prototypes. This patch converts the function signatures to have a prototype for the situations where the test is not specific to K&R C declarations. e.g., void func(); becomes void func(void); This is the twelfth batch of tests being updated (the end may be in sight soon though).
