d6856859d3 improvements for windows and libc integration 
* standard library knows if it is linking against libc and will
   sometimes call libc functions in that case instead of providing
   redundant definitions
 * fix infinite loop bug when resolving use declarations
 * allow calling the same C function from different C imports.
   closes #277
 * push more logic from compiler to std/bootstrap.zig
 * standard library provides way to access errno
   closes #274
 * fix compile error in standard library for windows
 * add implementation of getRandomBytes for windows

fa7c64ccd5 lazy analysis of top level declarations 
previously, we had lazy analysis of top level declarations,
but if a declaration was referenced within a compile-time
if or switch statement, that would still add the top
level declaration to the resolution queue.

now we have a declref ir instruction, which is only resolved
if we analyze the instruction. this takes into account comptime
branching.

1195994880 fix inability to write to global in some cases 
before, when we initialized a variable by copying the
initialization value, it made the internal const value
references point to a duplicate value, resulting in
a phony duplicate global value being updated instead of
the real on. now the behavior is as expected.

thanks to hoppetosse for pointing out this bug on IRC.
