Re-apply r249644: Handle inline stacks in gcov-encoded sample profiles. This fixes memory allocation problems by making the merge operation keep the profile readers around until the merged profile has been emitted. This is needed to prevent the inlined function names to disappear from the function profiles. Since all the names are kept as references, once the reader disappears, the names are also deallocated. Additionally, XFAIL on big-endian architectures. The test case uses a gcov file generated on a little-endian system. llvm-svn: 249724

The input gcov file has been generated on a little endian machine. Expect
failures on big endian systems.
[tests] Add host-byteorder-*-endian; update XFAILs of big-endian triples Summary: Triple components in `XFAIL` lines are tested against the target triple. Various tests that are expected to fail on big-endian hosts are marked as being `XFAIL` for big-endian targets. This patch corrects these tests by having them test against a new `host-byteorder-big-endian` feature.

Tests for sample profiles encoded in GCC's gcov format.
1- Show all functions. This profile has a single main() function with several
inlined callees.
RUN: llvm-profdata show --sample %p/Inputs/gcc-sample-profile.gcov | FileCheck %s --check-prefix=SHOW1
SHOW1: Function: main: 364084, 0, 6 sampled lines
SamplePGO - Add dump routines for LineLocation, SampleRecord and FunctionSamples llvm-svn: 253071

SHOW1: 2.3: inlined callee: _Z3fool: 243786, 0, 3 sampled lines
SHOW1: 1.3: inlined callee: _Z3bari: 0, 0, 2 sampled lines
SHOW1: 1.7: inlined callee: _Z3bari: 98558, 0, 2 sampled lines
SamplePGO - Sort samples by source location when emitting as text. When dumping function samples or writing them out as text format, it helps if the samples are emitted sorted by source location. The sorting of the maps is a bit slow, so we only do it on demand. llvm-svn: 253568

2- Convert the profile to text encoding and check that they are both
identical.
RUN: llvm-profdata merge --sample %p/Inputs/gcc-sample-profile.gcov --text -o - | llvm-profdata show --sample - -o %t-text
RUN: llvm-profdata show --sample %p/Inputs/gcc-sample-profile.gcov -o %t-gcov
RUN: diff %t-text %t-gcov
4- Merge the gcov and text encodings of the profile and check that the
counters have doubled.
RUN: llvm-profdata merge --sample --text %p/Inputs/gcc-sample-profile.gcov -o %t-gcov
RUN: llvm-profdata merge --sample --text %p/Inputs/gcc-sample-profile.gcov %t-gcov -o - | FileCheck %s --check-prefix=MERGE1
