Subject: [PATCH] JavaScriptCore: handle Carry in RISCV64 testFinalize switch

testFinalize() switches on ResultCondition but does not list the Carry
case, which makes every translation unit that includes
MacroAssemblerRISCV64.h emit:

  warning: enumeration value 'Carry' not handled in switch [-Wswitch]

The Carry condition cannot be produced by RISC-V test operations (the
ResultCondition enum declaration already comments it "<- not
implemented"), and the sibling switch elsewhere in this file already
groups Carry with Overflow/Signed/PositiveOrZero under
RELEASE_ASSERT_NOT_REACHED(). Add the missing case so testFinalize
matches that convention and the warning disappears.
