/// Parse a target data layout string, initializing the various TargetData
/// members along the way. A TargetData specification string looks like
/// "E-p:64:64-d:64-f:32-l:64-i:32-s:16-b:8-B:8" and specifies the
/// target's endianess, the alignments of various data types and
/// the size of pointers. The "-" is used as a separator and ":"
/// separates a token from its argument. Alignment is indicated in bits
/// and internally converted to the appropriate number of bytes.
///
/// Valid tokens:
/// <br>
/// <em>E</em> specifies big endian architecture (1234) [default]<br>
/// <em>e</em> specifies little endian architecture (4321) <br>
/// <em>p:[ptr size]:[ptr align]</em> specifies pointer size and alignment
/// [default = 64:64] <br>
/// <em>d:[align]</em> specifies double floating point alignment
/// [default = 64] <br>
/// <em>f:[align]</em> specifies single floating point alignment
/// [default = 32] <br>
/// <em>l:[align]</em> specifies long integer alignment
/// [default = 64] <br>
/// <em>i:[align]</em> specifies integer alignment
/// [default = 32] <br>
/// <em>s:[align]</em> specifies short integer alignment
/// [default = 16] <br>
/// <em>b:[align]</em> specifies byte data type alignment
/// [default = 8] <br>
/// <em>B:[align]</em> specifies boolean data type alignment
/// [default = 8] <br>
///
/// All other token types are silently ignored.
