112dd72c01 build: Remove unneeded file types.h
The file types.h has long been misnamed and overlaps with
functionality in the test helper routines.

794413ddd2 ec: Remove arch-specific redundant gf_nvect tests
The gf_{2-6}vect_dot_prod tests were kept in other_tests since the 5,6vect
functions were not strictly called by the higher level ec_encode_data() and
needed independent testing.  As this has now changed the extra tests can be
removed as redundant.

5eeb33f69c ec: add AVX512 ec functions with 5 and 6 outputs
Added AVX512 optimized functions to calculate the
GF(2^8) vector dot product with 5 and 6 outputs
at a time. Also added GF(2^8) vector multiply
AVX512 optimized functions with 5 and 6 accumulate.

d7848c1d05 Implement aarch64 neon for erasure code.
1.Replace below erasure code interfaces to arm neon interface by mbin_interface function.
	ec_encode_data
	gf_vect_mul
	gf_vect_dot_prod
	gf_vect_mad
	ec_encode_data_update

2.Utilise arm neon instrution to accelerate GF(2^8) set compute by 128bit registor.

57eed2f02b aarch64: Cleanup build issues
This patch addresses one build failure and fixes several build warnings
for Arm (some for x86 too).

- Fix dynamic relocation link failure of ld.bfd 2.30 on Arm
  [log] relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `xor_gen_neon' which may bind externally can not be used when making a shared object

- Add arch dependent "other_tests" to exclude x86 specific tests on Arm
  [log] isa-l/erasure_code/gf_2vect_dot_prod_sse_test.c:181: undefined reference to `gf_2vect_dot_prod_sse'

- Check "fread" return value to fix gcc warnings on Arm and x86
  [log] warning: ignoring return value of ‘fread’, declared with attribute warn_unused_result [-Wunused-result]
        fread(in_buf, 1, in_size, in_file);
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

- Fix issue of comparing "char" with "int" on Arm. "char" is unsigned
  on Arm by default, an unsigned char will never equal to EOF(-1).
  [Log] programs/igzip_cli.c:318:31: warning: comparison is always true due to limited range of data type [-Wtype-limits]
        while (tmp != '\n' && tmp != EOF)
                                  ^~

- Include <stdlib.h> to several files to fix build warnings on Arm
  [log] igzip/igzip_inflate_perf.c:339:5: warning: incompatible implicit declaration of built-in function ‘exit’
        exit(0);
        ^~~~

useful information in its current format.

82a6ac65dc ec: Determine exact conditions where gf_gen_rs_matrix works
Add a program calculating some of the exact conditions where gf_gen_rs_matrix
works, add comments stating these bounds to gf_gen_rs_matrix, and fix erasure
code test that violates the bounds.

Allows configure to again build in an external directory.  When building ISAL in
