// MemoryDataBuilder records and performs operations of following types on a memory buffer `buf`:
// 1. "Align": Align to a alignment `alignment`, which will ensure
// `buf.size() % alignment == 0` by adding padding bytes into the buffer
// if necessary;
// 2. "Data": Add `size` bytes of data bytes into buffer;
// 3. "Padding": Add `size` bytes of padding bytes into buffer;
// 4. "FillingFixed": Fill all `size` given (fixed) bytes into the memory buffer.
// Note that data bytes and padding bytes are generated seperatedly and designed to
// be distinguishable, i.e. data bytes have the second most significant bit set to 0 while padding
// bytes 1.
// We don't want testing data includes NaN or Inf, because according to WGSL spec an implementation
// may give indeterminate value if a expression evaluated to NaN or Inf, and in Tint generated
// HLSL reading a f16 NaN from buffer is not bit-pattern preserved (i.e. a NaN input may be changed
// to another NaN with different bit pattern). In bit representation of both f32 and f16, the first
// (most significant) bit is sign bit, and some biased exponent bits go after it (start from the
// second most significant bit). A float value is NaN or Inf if and only if all its exponent bits
// are 1. By setting the second most significant bit of every data byte to 0, we ensure that the
// second most significant bit of any float data in the buffer is 0, and therefore avoid generating
// NaN or Inf float datas.
