[XRay][compiler-rt][NFC] Expand the PIC test case for XRay
Summary:
Here we add a build with -ffunction-sections -fdata-sections and
Wl,--gc-sections to ensure that we're still able to generate XRay
traces.
This is just adding a test, no functional changes.
// Test to check if we handle pic code properly.
-// RUN: %clangxx_xray -fxray-instrument -std=c++11 -fpic %s -o %t
+// RUN: %clangxx_xray -fxray-instrument -std=c++11 -ffunction-sections \
+// RUN: -fdata-sections -fpic -fpie -Wl,--gc-sections %s -o %t
// RUN: XRAY_OPTIONS="patch_premain=true verbosity=1 xray_logfile_base=pic-test-logging-" %run %t 2>&1 | FileCheck %s
// After all that, clean up the output xray log.
