4fe088329c Work around CI failures for the ARM target 
These seem to have been introduced by recent LLVM changes.

* The instruction limit for vld*/vst* has been raised. This is not a
significant issue, it is only used for testing.
* vld*/vst* instructions are generated with overly strict alignments:
https://github.com/rust-lang/stdarch/issues/1217
* vtbl/vtbx instrinsics are failing intrinsic-test for unknown reasons.

211a00769c Improve intrinsic-test output formatting. 
This change is simple, but makes the generated tests much easier to
follow (and debug).

d2736197f7 Add --generate-only to intrinsic-test. 
This is useful for debugging.

7f2a7c09ef Fix intrinsic-test author handling. 
CARGO_PKG_AUTHORS is :-separated.

Also add myself to intrinsic-test authors.

05afebca4d Clean up intrinsic-test literals. 
- Ensure that C literals don't rely on undefined overflow behaviour.
- We don't need to use 'as' casts, so remove them.
- We weren't using allow(overflowing_literals), so remove it.
- Format FP bit values as hex.

This simplifies the test input initialisers in the generated files,
making them shorter and easier to debug.

1970299926 Remove unnecessary unsafety in intrinsic tests. 
This fixes "unnecessary `unsafe` block" warnings encountered when
building the generated rust_programs.

The only pattern that actually required `unsafe` was transmuting bit
patterns into floats. This patch uses the safe `from_bits` instead, but
because that isn't const, we have to make them local let-bound
variables.
