Emit & read more compressed bytecode by not emitting a bytecodeblock for

each basic block in function. Instead, just emit a stream of instructions,
chopping up basic blocks based on when we find terminator instructions. This
saves a fairly substantial chunk of bytecode space. In stripped, sample
cases, for example, we get this reduction in size:
197.parser: 163036 -> 137180: 18.8% reduction
254.gap : 844936 -> 689392: 22.6%
255.vortex: 621724 -> 528444: 17.7%

bytecode version number at all, though version 1.1 should not need to support
the old format.

*** Significantly speed up type resultion
...
This change speeds up type resolution by checking to see if a type is
recursive, and if it's not, using a more efficient algorithm.
This dramatically reduces bytecode loading time of kc++, reducing time-to-jit
kc++ --version to 17s from 33s

* Strength reduce several data structures which were left over from the

* Minor efficiency improvements
* Major efficiency improvement: In BytecodeParser::insertValue, do not allocate
a new ValueTab entry just because some value exists with a large type. This
dramatically reduces the number of allocations/deallocations performed by the
bytecode reader, and speeds up parsing of Kimwitu++ from 34s to 17s. This is
to help address PR127

ISO 9899 7.13.2.1 (3) says that "[...] the values of objects of automatic
...
storage duration that are local to the function containing the invocation of the
[...] setjmp macro that do not have volatile-qualified type and have been
changed between the setjmp invocation and longjmp call are indeterminate."
As such, we have to mark all variables in a function that uses 'invoke' as
volatile.
