c648fa3d06 Move condcodes.rs to a new crate, cranelift-codegen-shared 
This move allows the `IntCC`/`FloatCC` enums to be used in both meta (for predicate matching) and in codegen. To avoid breaking any code dependent on the previous location of condcodes.rs (`cranelift-codegen/src/condcodes.rs`), the module is re-exported under `cranelift_codegen::ir`.

Also fixes broken links to point to docs.rs; see
https://github.com/CraneStation/cranelift/pull/1041#issuecomment-532356880,
there doesn't currently seem to be a way to link to a type in a
dependent crate.

3418fb6e18 [codegen] reintroduce support for carry and borrow instructions in RI… (#1005) 
Reintroduce support for iadd carry variants and isub borrow variants for
RISC ISAs which had been removed in
https://github.com/CraneStation/cranelift/pull/961 and
https://github.com/CraneStation/cranelift/pull/962 because of the lack
of a proper flags register in RISC architectures.

ea919489ee [codegen] add encodings for iadd carry variants (#961) 
* [codegen] add encodings for iadd carry variants

Add encodings for iadd carry variants (iadd_cout, iadd_cin, iadd_carry)
for x86_32, enabling the legalization for iadd.i64 to work.

* [codegen] remove support for iadd carry variants on riscv

Previously, the carry variants of iadd (iadd_cin, iadd_cout and
iadd_carry) were being legalized for isa/riscv since RISC architectures
lack a flags register.

This forced us to return and accept booleans for these operations, which
proved to be problematic and inconvenient, especially for x86.

This commit removes support for said statements and all dependent
statements for isa/riscv so that we can work on a better legalization
strategy in the future.

* [codegen] change operand type from bool to iflag for iadd carry variants

The type of the carry operands for the carry variants of the iadd
instruction (iadd_cin, iadd_cout, iadd_carry) was bool for compatibility
reasons for isa/riscv. Since support for these instructions on RISC
architectures has been temporarily suspended, we can safely change the
type to iflags.

d64e454004 Improve uimm128 parsing 
This commit changes 128-bit constant parsing in two ways:
 - it adds the ability to use underscores to separate digits when writing a 128-bit constant in hexadecimal; e.g. `0x00010203...` can now be written as `0x0001_0203_...`
 - it adds a new mechanism for parsing 128-bit constants using integer/float/boolean literals; e.g. `vconst.i32x4 [1 2 3 4]`. Note that currently the controlling type of the instruction dictates how many literals to parse inside the brackets.

020e5987d3 Use little-endian ordering for CLIF vconst immediate 
Examining wasm-objdump revealed that it stores SIMD constants in little-endian order, e.g.:

000071 func[2] <test_const>:
 000072: fd 02 01 00 00 00 02 00 00 | v128.const 0x00000001 0x00000002 0x00000003 0x00000004
 00007b: 00 03 00 00 00 04 00 00 00 |
 000084: fd 0d 03                   | i32x4.extract_lane 3
 000087: 0b                         | end

This change avoids confusion by making the CLIF representation use little-endian order as well.
