Some operations make polkavm program size bloats

[indirection42]

I found this trivial operation bloats the polkavm program size (from 470B to 4KB)

XCQ/poc/guests/query-balance-fungibles/src/main.rs

Lines 28 to 29 in 94b1c13

	let res_bytes = unsafe { core::slice::from_raw_parts(res_ptr, res_len as usize) };
	sum += u64::from_le_bytes(res_bytes.try_into().unwrap());

compared to

sum += unsafe{ core::ptr::read_volatile(res_ptr as *const u64); }

I use polkatool to disassemble the program, and found the bloating part is Code size which goes from 287bytes to 3228 bytes.
