This gets rid of almost LLVM targets unconditionally depending on intrinsic_gen.

Clang's modules still have weird dependencies and hard to remove intrinsics_gen in better way.
Then, it'd be better to give whole clang targets depend on intrinsic_gen.

[X86] Add patterns for memory forms of SARX/SHLX/SHRX with careful complexity adjustment to keep shift by immediate using the legacy instructions.

These patterns were only missing to favor using the legacy instructions when the shift was a constant. With careful adjustment of the pattern complexity we can make sure the immediate instructions still have priority over these patterns.

Check the actual memory type stored and not the extended value size
when considering if truncated store merge is worthwhile.

llvm-svn: 308822

As discussed on llvm-dev I've implemented the first basic steps towards
llvm-objcopy/llvm-objtool (name pending).

This change adds the ability to copy (without modification) 64-bit
little endian ELF executables that have SHT_PROGBITS, SHT_NOBITS,
SHT_NULL and SHT_STRTAB sections.

MIR SRADI uses instruction template XSForm_1rc which declares Defs = [CARRY]. But MIR SRADI_32 uses instruction template XSForm_1, and it doesn't declare such implicit definition. With patch D33720 it causes wrong code generation for perl.

This patch adds the implicit definition.

This includes the hash table, the address map, and the thunk table and
section offset table. The last two are only used for incremental
linking, which LLD doesn't support, so they are less interesting. The
hash table is particularly important to get right, since this is the one
of the streams that debuggers use to translate addresses to symbols.

Summary: Currently the ThinLTO minimized bitcode file only strip the debug info, but there is still a lot of information in the minimized bit code file that will be not used for thin linker. In this patch, most of the extra information is striped to reduce the minimized bitcode file. Now only ModuleVersion, ModuleInfo, ModuleGlobalValueSummary, ModuleHash, Symtab and Strtab are left. Now the minimized bitcode file size is reduced to 15%-30% of the debug info stripped bitcode file size.

Separated out the profitability from the safety analysis for multiexit
loop unrolling. Currently, this is an NFC because profitability is true
only if the unroll-runtime-multi-exit is set to true (off-by-default).
