Fix test for D77924.

[enh]

Summary

The trailing 'L' was missing in the expectation.

[vvereschaka]

The test got failed again. I got the following output:

ubuntu@jetson8:~$ ./t.tmp.exe
Testing 29715 symbols.
1ILeeeEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE -> <-0x1.cecececececececececececececep+11983L
Got instead: <-0x1.cecececececececececececececep+11983L>
t.tmp.exe: C:/buildbot/temp/llvm-project/libcxxabi/test/test_demangle.pass.cpp:30001: void testFPLiterals(): Assertion `false' failed.
Aborted (core dumped)

looks like it does not expect trailing >.

Address vvereschaka's comment.

man, debugging without a working machine is hard. thanks again!

[vvereschaka]

I understand, not a problem. I'm testing the updated patch.

[vvereschaka]

It works fine now for me

@enh,
may be let's commit the fix? This problem keeps the builder in red for a week already.

[srhines]

Yes, let's just submit this now. If it breaks further, then we can consider other options. I'm not sure why there is a separate libc++abi reviewer listed here.

[enh]

sorry about the breakage... thanks for testing on real hardware!
