Shengchen Kan 87c86aa6b9 [X86,SimplifyCFG] Support hoisting load/store with conditional faulting (Part I) (#96878) 
This is simplifycfg part of
https://github.com/llvm/llvm-project/pull/95515

In this PR, we support hoisting load/store with conditional faulting in
`SimplifyCFGOpt::speculativelyExecuteBB` to eliminate conditional
branches.
This is for cases like
```
void test (int a, int *b) {
  if (a)
   *b = a;
}
``` 

In the following patches, we will support the hoist in
`SimplifyCFGOpt::hoistCommonCodeFromSuccessors`.
That is for cases like
```
void test (int a, int *c, int *d) {
  if (a)
   *c = a;
  else 
   *d = a;
}
```
