Splitting thinlto.ll test file and renaming other test files.

Summary

Splitting thinlto.ll test file and renaming other test files.

[ruiu]

Looks great. Thank you for doing this.

lld/test/ELF/lto/thinlto-index-file.ll

9–14

Could you factor this test to a separate file?

[ruiu]

lld/test/ELF/lto/thinlto-index-file.ll

10

Now that you have only one FileCheck, you can remove --check-prefix and replace IN1 with CHECK.

FileCheck %s < %tlinkobjfile

is more straightforward than cat.

Please don't use a long file name because this file is short enough. %tlinkedobfile ->%t.idx

lld/test/ELF/lto/thinlto-no-index.ll

4

%t.o, %t2.o and %t4.o look a bit odd. Please rename them %t1.o, %t2.o and %t3.o.

lld/test/ELF/lto/thinlto-obj-path.ll

9

Remove -check-prefix.
