[PATCH] MATCH: [PR111432] Simplify `a & (x | CST)` to a when we know that (a & ~CST) == 0

This adds the simplification `a & (x | CST)` to a when we know that `(a & ~CST) == 0`. In a similar fashion as `a & CST` is handle. I looked into handling `a | (x & CST)` but that I don't see any decent simplifications happening. OK? Bootstrapped and tested on x86_linux-gnu with no regressions.

[PATCH] Power10: Add options to disable load and store vector pair.

[PATCH v18 03/40] c++: Accept the use of non-function-like built-in trait identifiers

This patch accepts the use of non-function-like built-in trait identifiers. Specifically, we check if the subsequent token is '(' for ordinary built-in traits or is '<' only for the special __type_pack_element built-in trait. If the same identifiers are used in other cases, the parser treats them

Since RID_MAX soon reaches 255 and all built-in traits are used approximately once in a C++ translation unit, this patch removes all RID values for built-in traits and uses gperf to look up the specific trait. Rather than holding traits as keywords, we set all trait identifiers as cik_trait, which
