Since now we can distinguish between def and use according to
the variable's location, there is no need to keep two variable
prefixes.
Also reformat tests to use the value generating instruction
format ("<result-id> = <opcode> <operand>..").
Fix the bug that TextAdvance() forgot to skip whitespace at the
beginning of the next line after a comment line.
Fix the bug that TextAdvanceLine() increase line number after going
over a character.
For enum Capability and enum Op, not all newly added enumerants are
registered into capabilityInfoEntries and opcodeTableEntries yet.
That will come in following commits.
Avoid cmake target conflicts
This makes it easier to include spirv-tools into larger cmake-based
projects, which may already include glslang or googletest. It is
currently difficult to do this because of target clashes and a
hardcoded googletest path.
glslang defines a target named SPIRV, so rename ours to SPIRV-TOOLS.
A googletest subdirectory may already be added somewhere else, so if
the external/googletest directory does not exist, probe whether there
is a gtest target defined already. This makes spirv-tools work
out-of-the-box when plopped into a larger project already containing
googletest; otherwise the README.md procedure still works as before.

Fix failing test
The generator number is set to `SPV_GENERATOR_KHRONOS` in the
`spvBinaryHeaderSet` function, so tests should catch up.
