This patch is a follow up on https://reviews.llvm.org/D81627.
In addition to default -fno-gpu-rdc case, this patches let
HIP toolchain not use llvm-link/opt/llc to link device code
for -fgpu-rdc case. Instead, uses standard lto.
This will eliminate some redundant optimizations and speed
up the compilation/linking.
Differential Revision: https://reviews.llvm.org/D81861
Summary:
Tooling around DWARF 5 is still not mature enough for this to be a sane
default, and the AMDGPU and HIP toolchains should agree on a single
default.

Effectively reverts r337612. The issues that cropped up with the last
attempt appear to have gone away.

There were some problems unearthed with version 5,
which I am going to look at.

In DWARF v5 the Line Number Program Header is extensible, allowing values with
new content types. This vendor extension to DWARF v5 allows source text to be
embedded directly in the line tables of the debug line section.
Add new flag (-g[no-]embed-source) to Driver and CC1 which indicates
that source should be passed through to LLVM during CodeGen.

Summary:
Now that LLVM is emitting version 2 of the AMD code object, we can
start using lld again for linking instead of our custom tool.

The problem this time was the /clang matching the InstalledDir line.
Now we just use regular expressions which are more flexible, if a bit less
readable, than CHECK+CHECK-SAME.
llvm-svn: 248031
CHECK-LABEL assumes that there is only one occurrence of the match.
The output looks like:
clang version 3.8.0 (trunk 247999)
....
/path/to/build/dir/bin/clang-3.8 ....
If the path contains lld, the second CHECK-LABEL matches it and we fail since
there is no -cc1as between clang and lld.
llvm-svn: 248029
Summary:
This is a minimal toolchain, which sets the integrated assembler as default,
and uses lld for linking.
