The codegen for non-inlined version is "quite ugly" as it emits some
checks to make sure the initialization routine is properly executed
because the compiler does not see how the TLS object is initialized.
This leads to some `callq 0x0` junk in the final outputs.

For codegen details, see https://godbolt.org/z/rb5qYj3vY.

While looking through the list of includes for #99693 I found these
includes that also need to be cleaned up. I removed the extra includes
in expm1.cpp, but the include in thread.h needs more attention so I just
marked it with a todo.

This patch fixes:

randomness.h and getauxval.cpp were passing ssize_t as size_t
kernel_statx.h was assigning an uint64_t to uintptr_t
fopencookie.cpp was trying to create a FileIOResult using ssize_t but the constructor expected a size_t
thread.h was trying to call free_stack (which takes a size_t) with an unsigned long long. free_stack does the calculations using uintptr_t, so I changed the passing values to size_t
