ObjectFileBreakpad: Implement sections Summary: This patch allows ObjectFileBreakpad to parse the contents of Breakpad files into sections. This sounds slightly odd at first, but in essence its not too different from how other object files handle things. For example in elf files, the symtab section consists of a number of "records", where each record represents a single symbol. The same is true for breakpad's PUBLIC section, except in this case, the records will be textual instead of binary. To keep sections contiguous, I create a new section every time record type changes. Normally, the breakpad processor will group all records of the same type in one block, but the format allows them to be intermixed, so in general, the "object file" may contain multiple sections with the same record type.

Breakpad: Parse Stack CFI records Summary: This patch adds support for parsing STACK CFI records from breakpad files. The expressions specifying the values of registers are not parsed.The idea is that these will be handed off to the postfix expression -> dwarf compiler, once it is extracted from the internals of the NativePDB plugin.
