gcc: arm: linux-eabi: fix handling of armv4 bx fixups when linking

The bpabi.h header already sets up defines to automatically use the
--fix-v4bx flag with the assembler & linker as needed, and creates a
default assembly & linker spec which uses those.  Unfortunately, the
linux-eabi.h header clobbers the LINK_SPEC define and doesn't include
the v4bx define when setting up its own.  So while the assembler spec
is retained and works fine to generate the right relocs, building for
armv4 targets doesn't invoke the linker correctly so all the relocs
get processed as if we had an armv4t target.

You can see this with -dumpspecs when configuring gcc for an armv4
target and using --with-arch=armv4:
$ armv4l-unknown-linux-gnueabi-gcc -dumpspecs |& grep -B 1 fix-v4bx
*subtarget_extra_asm_spec:
.... %{mcpu=arm8|mcpu=arm810|mcpu=strongarm*|march=armv4|mcpu=fa526|mcpu=fa626:--fix-v4bx} ...

With this fix in place, we also get the link spec:
$ armv4l-unknown-linux-gnueabi-gcc -dumpspecs |& grep -B 1 fix-v4bx
*link:
...  %{mcpu=arm8|mcpu=arm810|mcpu=strongarm*|march=armv4|mcpu=fa526|mcpu=fa626:--fix-v4bx} ...

And all my hello world tests / glibc builds automatically turn the
bx insn into the 'mov pc, lr' insn and all is right in the world.

This patch fixes PR bootstrap/57077.

This patch fixes PR bootstrap/57077. Certain new uses of apply_probability
are actually scaling the counts up, and the scale factor should not
be treated as a probability as the value may exceed REG_BR_PROB_BASE.
One example (from the PR) is when scaling counts up in LTO when merging
profiles. Another example I found when preparing the patch to use
the rounding divide in more places is when inlining COMDAT functions.

Add new helper function apply_scale that does the scaling without
the probability range check. I audited the new uses of apply_probability
and changed the calls as appropriate.

This patch is the main part of a consolodation of the hash_table
patches to the cxx-conversion branch for files not under gcc/config.

Update various hash tables from htab_t to hash_table.
Modify types and calls to match.

* tree-parloops.c'reduction
* tree-parloops.c'name_to_copy

Fold reduction_info_hash and reduction_info_eq into new struct
reduction_hasher.  Fold name_to_copy_elt_eq and name_to_copy_elt_hash
into new struct name_to_copy_hasher.

* trans-mem.c'tm_log

Fold tm_log_hash, tm_log_eq, tm_log_free into new struct log_entry_hasher.

* trans-mem.c'tm_memopt_value_numbers

Fold tm_memop_hash, tm_memop_eq into new struct tm_memop_hasher.

* tree-ssa-strlen.c'decl_to_stridxlist_htab

Fold decl_to_stridxlist_hash into new struct stridxlist_hasher.

Fold htab_inv_expr_hash and htab_inv_expr_eq into new struct
iv_inv_expr_hasher.

Equiv renamed to val_ssa_equiv because of name ambiguity with local variables.

Fold equiv_hash, equiv_eq and equiv_free into new struct val_ssa_equiv_hasher.

Renamed variables equiv_hash_elt to an_equiv_elt because of name ambiguity
with struct type.  Changed equiv_hash_elt_p to an_equiv_elt_p to match.

* tree-ssa-phiopt.c'seen_ssa_names

Fold name_to_bb_hash and name_to_bb_eq into new struct ssa_names_hasher.

* tree-ssa-structalias.c'pointer_equiv_class_table

Fold equiv_class_label_hash and equiv_class_label_eq into new
struct equiv_class_hasher.

Fold shared_bitmap_hash and shared_bitmap_eq into new struct
shared_bitmap_hasher.

New struct tree_int_map_hasher.

* tree-sra.c'candidates

Fold uid_decl_map_hash and uid_decl_map_eq into new struct
uid_decl_hasher.  This change moves the definitions from tree-ssa.c
into tree-sra.c and removes the declarations from tree-flow.h

tree-browser.c

Remove stale declaration of removed TB_parent_eq.
Fix template parameter for base class to match value_type.

gimple.h

Use gimplify_hasher::hash rather than gimple_tree_hash in the
  assertion check.
Change return values to match return type. (I.e. no conversions.)

are used in few places.

Remove unused:

htab_t scop::original_pddrs
SCOP_ORIGINAL_PDDRS

Remove unused:

insert_loop_close_phis
insert_guard_phis

Move the declaration of hash_table <alloc_pool_hasher> alloc_pool_hash
in alloc-pool.c to after the method definitions for its parameter
class.

* ggc-common.c'loc_hash
* ggc-common.c'ptr_hash

Add a new hash_table method elements_with_deleted to meet the needs of
gcc-common.c.

Correct many methods with parameter types compare_type to the correct
value_type.  (Correct code was unlikely to notice the change, but
incorrect code will.)

* tree-complex.c'complex_variable_components
* tree-parloops.c'eliminate_local_variables_stmt::decl_address
* tree-parloops.c'separate_decls_in_region::decl_copies

Move hash table declarations to a new tree-hasher.h, to resolve
compilation dependences and because they are used in few places.

* lto-streamer.h'output_block::string_hash_table
* lto-streamer-in.c'file_name_hash_table
* lto-streamer.c'tree_htab

The struct string_slot moves from data-streamer.h to lto-streamer.h to
resolve compilation dependences.

Tested on x86_64.
