[CodeGen] Convert tests to opaque pointers (NFC) Conversion performed using the script at: https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34 These are only tests where no manual fixup was required.

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 tenth batch of tests being updated (there are a significant number of other tests left to be updated).

Fixup blocks codegen for { __block i; i = rhs(); }, we want the rhs evaluated first. This can also improve codegen just a bit as we might have another register to play with for the evaluation of the rhs. llvm-svn: 72226

Distinguish `__block` variables that are captured by escaping blocks from those that aren't. This patch changes the way __block variables that aren't captured by escaping blocks are handled: - Since non-escaping blocks on the stack never get copied to the heap (see https://reviews.llvm.org/D49303), Sema shouldn't error out when the type of a non-escaping __block variable doesn't have an accessible copy constructor. - IRGen doesn't have to use the specialized byref structure (see https://clang.llvm.org/docs/Block-ABI-Apple.html#id8) for a non-escaping __block variable anymore. Instead IRGen can emit the variable as a normal variable and copy the reference to the block literal. Byref copy/dispose helpers aren't needed either. This reapplies r343518 after fixing a use-after-free bug in function Sema::ActOnBlockStmtExpr where the BlockScopeInfo was dereferenced after it was popped and deleted. rdar://problem/39352313 Differential Revision: https://reviews.llvm.org/D51564 llvm-svn: 343542
