This adds -no-opaque-pointers to clang tests whose output will
change when opaque pointers are enabled by default. This is
intended to be part of the migration approach described in
https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.
The patch has been produced by replacing %clang_cc1 with
%clang_cc1 -no-opaque-pointers for tests that fail with opaque
pointers enabled. Worth noting that this doesn't cover all tests,
there's a remaining ~40 tests not using %clang_cc1 that will need
a followup change.

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.

[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.

This addresses a regression introduced with SVN r219393. A block may be
contained within another block. In such a scenario, we would end up within a
BlockDecl, which is not a NamedDecl (as the names are synthesised). The cast to
a NamedDecl of the DeclContext would then assert as the types are unrelated.
Restore the mangling behaviour to that prior to SVN r219393. If the current
block is contained within a BlockDecl, walk up to the parent DeclContext,
recursively, until we have a non-BlockDecl. This is expected to be a NamedDecl.
Add in a couple of asserts to ensure that the assumption that we only encounter
a block within a NamedDecl or a BlockDecl.
