3e2046214c Try to fix some things
* shift so that no panics are generated (otherwise results in linker error)
* no_std as insurance to not get into issues with errors like "cannot satisfy dependencies so `rustc_i128` only shows up once" (pure guessing here, but it doesn't hurt...)

64de4e2731 Fix LEB128 to work with the stage1
Stage 1 can’t really handle negative 128-bit literals, but an equivalent bit-not is fine

b0e55a83a8 Such large. Very 128. Much bits.
This commit introduces 128-bit integers. Stage 2 builds and produces a working compiler which
understands and supports 128-bit integers throughout.

The general strategy used is to have rustc_i128 module which provides aliases for iu128, equal to
iu64 in stage9 and iu128 later. Since nowhere in rustc we rely on large numbers being supported,
this strategy is good enough to get past the first bootstrap stages to end up with a fully working
128-bit capable compiler.

In order for this strategy to work, number of locations had to be changed to use associated
max_value/min_value instead of MAX/MIN constants as well as the min_value (or was it max_value?)
had to be changed to use xor instead of shift so both 64-bit and 128-bit based consteval works
(former not necessarily producing the right results in stage1).
