commit 0ade9b319e8943cc5252f1f53cd2927a28fbf1dc
Author: Daniel Llorens <[email protected]>

Fix compilation of rank 0 typed array literals
* module/system/vm/assembler.scm (simple-uniform-vector?): array-length
fails for rank 0 arrays; fix the shape condition.
* test-suite/tests/arrays.test: test reading of #0f64(x) in compilation
context.
