hyeongyukim aacfbb953e [Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default 
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.

Jeroen Dobbelaere 46757ccb49 [clang] functions with the 'const' or 'pure' attribute must always return. 
As described in
* https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-pure-function-attribute
* https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-const-function-attribute

An `__attribute__((pure))` function must always return, as well as an `__attribute__((const))` function.

Michael Liao 5dbf80cad9 [clang][codegen] Annotate `correctly-rounded-divide-sqrt-fp-math` fn-attr for OpenCL only. 
- `-cl-fp32-correctly-rounded-divide-sqrt` is an OpenCL-specific option
  and `correctly-rounded-divide-sqrt-fp-math` should be added for OpenCL
  at most.

Tim Northover c46827c7ed LLVM IR: Generate new-style byval-with-Type from Clang 
LLVM IR recently added a Type parameter to the byval Attribute, so that
when pointers become opaque and no longer have an element type the
information will still be present in IR.

For now the Type parameter is optional (which is why Clang didn't need
this change at the time), but it will become mandatory soon.

Sanjay Patel 7b61dc7a23 [CodeGen] change const-ness of complex calls 
After clarification about the C standard, POSIX, and implementations:
The C standard allows errno-setting, and it's (unfortunately for optimization) even 
more clearly stated in the newer additions to the standards.

We can leave these functions as always constant ('c') because they don't 
actually do any math and therefore won't set errno:

Sanjay Patel 040fbe3027 [CodeGen] split math and complex tests into separate files; NFCI 
The files are already large, and we may need to add even more RUNs to 
distinguish differences based on OS, environment, or other platform things.
