bcc268a3cd [clippy] Fix a few clippy issues in lib/codegen/; 
- don't generate "&& true" when generating instruction eq() fn;
- use more Self;
- use subsec_millis instead of subsec_nanos and divide;
- coalesce two ifs;

632bbf2008 Permit {s,u}{div,rem}_imm instructions to be potentially trapping. 
The documentation for these instructions suggests that immediate values
which could lead to trapping should be invalid.

While it seems nice to have these instructions be always non-trapping,
it's also nice to say that the `_imm` forms of instructions are
interchangeable with the corresponding non-`_imm` forms accompanied
by `iconst` instructions.

276ba8b97d Support systems which don't have a "python" command. (#386) 
Add support for finding an appropriate python command on systems which
don't have "python". Try "python3" and "python2.7".

Fixed #381.

8f3c49bc6c Update more references to "global variables".

7bed3426a7 Adds decoration to the verifier errors. (#375) 
* Adds decoration to the verifier errors.

example:

function %bad(i32) fast {
ebb0(v0: i32):
    brnz.i32 v0, ebb1
    return
    ^~~~~~

verifier inst1: Internal return not allowed with return_at_end=1

ebb1:
    trapz.i32 v0, user6
    return
}

Fixes #68

c5aad1eb5f Add support for macho relocations. (#378) 
This requires splitting X86PCRel4 into two separate relocations, to
distinguish the case where the instruction is a call, as Mach-O uses a
different relocation in that case.

This also makes it explicit that only x86-64 relocations are supported
currently.

d209137149 Rename TargetIsa's emit_function to emit_function_to_memory. 
This reflects the fact that it takes a concrete `MemoryCodeSink` rather than
a `CodeSink` trait object.

Dan Gohman
6971ae1c26 Export CodegenError and CodegenResult at the top level. 
Make cretonne-codegen's `result` module private, and instead just export
`CodegenError` and `CodegenResult` at the top level of the
cretonne-codegen crate. This makes them more consistent with Result and
Error types in other cretonne crates.

02e34d1bf7 Make CtonError parameterized on the result type.

13f22065a2 Rename verifier's Result and Error. 
This provides consistency with similar types in other parts of
Cretonne, and avoids shadowing `Result` from the standard prelude.

0daa560368 Accept redundant alias definitions. 
In the text format, allow aliases to be defined multiple times, as long
as they're always aliasing the same value.

write.rs is already emitting redundant aliases, because it emits them at
their uses, so this change allows the parser to be able to parse such
code.
