Regression range is accurate and points to 2ca420e46c1e6944e2f22b2a2414740aa01c5f3b. Unfortunately I cannot assign the issue to Choongwoo Han directly, assigning to Jakob instead. Reproduces nicely as follows ...

$ ./out/x64.debug/d8 -e 'Reflect.has(new Uint8Array())'

#
# Fatal error in ../../src/compiler/code-assembler.cc, line 1580
# Type cast failed in CAST(key) at ../../src/code-stub-assembler.cc:7137
  Expected String but found #undefined

The checked node and used node were mismatched. It checked if
"var_unique" is a string, but it used "key" which may not be a string.
