If an inlined kernel is called in a loop, the launch point alloca would
lead to increasing stack usage every time the kernel is invoked. This
could make the application run out of stack space and crash. This problem
is fixed by using the alloca insertion point while creating the alloca instruction.

Two another atomic compare capture forms, `{ v = x; expr-stmt }` and `{ expr-stmt; v = x; }`
where `expr-stmt` could be `cond-expr-stmt` are missing.

D127041 introduced the support for `fmax` and `fmin` such that we can also reprent
`atomic compare` and `atomic compare capture` with `atomicrmw` instruction. This
patch simply lifts the limitation we set before.
Depend on D127041.

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.
