Introduce a new LIBOMP_INSTALL_VARIABLES cache variable that can be used
to disable creating libgomp and libiomp5 aliases on 'make install'.
Those aliases are undesired e.g. on Gentoo systems where libomp is used
purely by clang.

This is a follow-up to r268778 that adds a couple of missing cases,
most notably orphaned compile units.

llvm-svn: 281508

Summary:
This patch uses the instruction CPUID to verify that FXSAVE, XSAVE, AVX
and MPX are supported by the target hardware. In case the HW supports XSAVE,
and at least one of the extended register sets, it further checks if the
target software has the kernel support for such features, by verifying that
their XSAVE part is correctly managed.

Summary:
Function __asan_default_options is called by __asan_init before the
shadow memory got initialized. Instrumenting that function may lead
to flaky execution.

As the __asan_default_options is provided by users, we cannot expect
them to add the appropriate function atttributes to avoid
instrumentation.

Until AVX512DQ we only support i64/vXi64 sitofp conversion as scalars.

This patch sees if the sign bit extends far enough that we can truncate to a i32 type and then perform sitofp without loss of precision.

This addresses a TODO to handle operations besides and. This
also starts eliminating no-op operations with a constant that

Move the definition of `getTriple()` into the header.  It would just call
`getTarget().getTriple()`.  Inline the definition to allow the compiler to see
the same amount of the layout as previously.  Remove the more verbose
`getTarget().getTriple()` in favour of `getTriple()`.

This patch moves the processing of pointer induction variables in
collectLoopUniforms from the consecutive pointer phase of the analysis to the
phi node phase. Previously, if a pointer induction variable was used by both a
scalarized non-memory instruction as well as a vectorized memory instruction,
we would incorrectly identify the pointer as uniform. Pointer induction
variables should be treated the same as other phi nodes. That is, they are
uniform if all users of the induction variable and induction variable update
are uniform.

If a constant is unamed_addr and is only used within one function, we can save
on the code size and runtime cost of an indirection by changing the global's storage
to inside the constant pool. For example, instead of:

      ldr r0, .CPI0
      bl printf
      bx lr
    .CPI0: &format_string
    format_string: .asciz "hello, world!\n"

We can emit:

      adr r0, .CPI0
      bl printf
      bx lr
    .CPI0: .asciz "hello, world!\n"

This can cause significant code size savings when many small strings are used in one
function (4 bytes per string).

[asan] Enable -asan-use-private-alias on Darwin/Mach-O, add test for ODR false positive with LTO (compiler-rt part)

The '-asan-use-private-alias’ option (disabled by default) option is currently only enabled for Linux and ELF, but it also works on Darwin and Mach-O. This option also fixes a known problem with LTO on Darwin (https://github.com/google/sanitizers/issues/647). This patch enables the support for Darwin (but still keeps it off by default) and adds the LTO test case.
