Turning on `enable_noundef_analysis` flag allows better codegen by removing freeze instructions.
I modified clang by renaming `enable_noundef_analysis` flag to `disable-noundef-analysis` and turning it off by default.
Test updates are made as a separate patch: D108453

[Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default (2)
This patch updates test files after D105169.
Autogenerated test codes are changed by `utils/update_cc_test_checks.py,` and non-autogenerated test codes are changed as follows:
(1) I wrote a python script that (partially) updates the tests using regex: {F18594904} The script is not perfect, but I believe it gives hints about which patterns are updated to have `noundef` attached.
(2) The remaining tests are updated manually.

body of global block invoke functions.
This commit fixes an infinite loop in IRGen that occurs when compiling
the following code:
void FUNC2() {
static void (^const block1)(int) = ^(int a){
if (a--)
block1(a);
};
}
This is how IRGen gets stuck in the infinite loop:
1. GenerateBlockFunction is called to emit the body of "block1".
2. GetAddrOfGlobalBlock is called to get the address of "block1". The
function calls getAddrOfGlobalBlockIfEmitted to check whether the
global block has been emitted. If it hasn't been emitted, it then
tries to emit the body of the block function by calling
GenerateBlockFunction, which goes back to step 1.
This commit prevents the inifinite loop by building the global block in
GenerateBlockFunction before emitting the body of the block function.

Instead of always displaying the mangled name, try to do better
and get something closer to regular functions.
Recommit r287039 (that was reverted in r287039) with a tweak to
be more generic, and test fixes!

Mangling for blocks defined within blocks in an ObjectiveC context were also
broken by SVN r219393. Because the code in mangleName assumed that the code was
either C or C++, we would trigger assertions when trying to mangle the inner
blocks in an ObjectiveC context.
Add a test and use the ObjectiveC specific mangling when dealing with an
ObjectiveC method declaration.
