refactor code responsible for moving data in the compiler
...
This is partially to address incorrect code generation for 64-bit
floating-point values on x86_32 and partially to reduce unnecessary
moves.

fix order-of-operations bug in compile loop
...
The code was capturing branch snapshots too early - before the call to
populateSources which might perform further moves.

visit all frame locations in resolveOriginalSites
...
Previously, we only visited frame locations containing values, but
this invited the possibility of reusing the same site for two
locations in some cases.

replace hasMoreThanOneSite with uniqueSite; rename Value fields
...
uniqueSite also checks, if applicable, to see if the second word of a
value shares the specified site with the first value as its sole site.
Also renamed a couple of fields in Value for clarity.

replace compare and branch instructions with combined versions
...
This allows the assembler to see the operand types of the comparison
and the condition for jumping in the same operation, which is
essential for generating efficient code in cases such as
multiple-precision compare-and-branch.

freeze sites for dead values in resolveOriginalSites

Previously, we simply removed the element from the sites array, but
this led to problems when the junction sites are shared among multiple
junctions such that the value at a given index is live at one junction
and dead at another.
